[kamailio/kamailio] Memory usage increases everytime tls.reload is executed (Issue #3823)
by Sebastian Denz 10 Jul '26

10 Jul '26

### Description We are using Kamailio 5.7.4 on Debian 12 (from http://deb.kamailio.org/kamailio57) with rtpengine as an Edgeproxy for our clients. The instance terminates SIP/TLS (with Cliencertificates) and forwards the SIP Traffic to internal systems. After some days we are getting errors like this `tls_complete_init(): tls: ssl bug #1491 workaround: not enough memory for safe operation: shm=7318616 threshold1=8912896` First we thought Kamailio just doesnt have enough memory, so we doubled it.. But after some days the Logmessage (and Userissues) occured again. So we monitored the shmmem statistics and found that used and max_used are constantly growing til it reaches the limit. As i mentioned we are using client-certificates and so we are also using the CRL feature. We do have a systemd-timer which fetches the CRL every hour and runs 'kamcmd tls.reload' when finished. Our tls.cfg looks like this: ``` [server:default] method = TLSv1.2+ private_key = /etc/letsencrypt/live/hostname.de/privkey.pem certificate = /etc/letsencrypt/live/hostname.de/fullchain.pem ca_list = /etc/kamailio/ca_list.pem ca_path = /etc/kamailio/ca_list.pem crl = /etc/kamailio/combined.crl.pem verify_certificate = yes require_certificate = yes [client:default] verify_certificate = yes require_certificate = yes ``` After testing a bit we found that every time tls.reload is executed Kamailio consumes a bit more memory which eventually leads to all the memory being consumed which leads to issues for our users. See following example: ``` [0][root@edgar-dev:~]# while true ; do /usr/sbin/kamcmd tls.reload ; /usr/sbin/kamcmd core.shmmem ; sleep 1 ; done Ok. TLS configuration reloaded. { total: 268435456 free: 223001520 used: 41352552 real_used: 45433936 max_used: 45445968 fragments: 73 } Ok.

[kamailio/kamailio] ims_diameter_server not freeing shared memory (Issue #4116)
by MGrimby 20 May '26

20 May '26

### Description I have run in to an issue when sending diameter requests using the ims_diameter_server module. Shared memory keeps increasing and are not being freed until restart of kamailio. This leads to all shared memory is being used and no more are able to be allocated. This only happens when the request is sent synchronously. When sent asynchronously shared memory is being freed as far as I can see. Following functions have been used for sending requests. diameter_request([peer], appid, commandcode, message) diameter_request_async([peer], appid, commandcode, message) ### Troubleshooting Sent a bunch of diameter requests and verified that shared memory for the following functions are not freed. do_receive(600): AAATranslateMessage(500): AAACreateAVP(137): #### Reproduction It's possible to reproduce by sending sync diameter request and verify shared memory.

[kamailio/kamailio] presence: preserve etag uniqueness when marking presentity for removal (PR #4275)

UNIQUE KEY `presentity_idx` (`username`,`domain`,`event`,`etag`), ``` This approach breaks the uniqueness of etag, which is intended to differentiate records , especially in cases such as parallel calls, or when using kamailio as a forking proxy. Instead of overwriting the etag with the static offline marker, this patch appends the marker to the existing etag value. This ensures the offline flag is retained while preserving the uniqueness of the etag. The deletion query was also updated accordingly: it now identifies offline records using a LIKE '%*#-OFFLINE-#*' clause. Based on testing, the duplicate key errors no longer occur, and the cleanup logic now behaves as expected. This patch improves the reliability of presentity cleanup without requiring schema or index changes. Please consider merging into master. Thanks!

[kamailio/kamailio] Issue with usrloc 'handle_lost_tcp' and dmq_usrloc 'usrloc_delete' (Issue #3479)
by alternatenetwork 02 May '26

02 May '26

### Description When a TLS connection is closed and handle_lost_tcp=1 the entry is deleted for usrloc. This deletion is not synced via DMQ even though usrloc_delete=1. There is also an issue on the same server if a re-registration happens right after before the timeout was supposed to expire then $var(sv_res) = 2 even though the usrloc table is empty. So it seems like the way handle_lost_tcp deletes is not deleting fully in registrar. usrloc db_mode is 0 ### Troubleshooting #### Reproduction Setup 2 servers with DMQ and close the TCP connection. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.6.1 (x86_64/linux) d8f98b flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: d8f98b compiled on 19:05:04 Aug 16 2022 with gcc 8.3.0 ``` * **Operating System**:  ``` Debian 10 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3479 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Kamailio 5.4.x dialog profiles functionality dead-lock on certain high-load scenarios (Issue #2923)
by Henning Westerholt 03 Apr '26

03 Apr '26

### Description The Kamailio 5.4.x dialog profiles functionality can lead to dead-lock on certain high-load scenarios. The Kamailio dialog profiles are used to track parallel channels for about 200 outgoing PSTN carrier interconnections. During high traffic times (like several thousands parallel calls) the Kamailio server will frequently (e.g. hourly) goes into an end-less loop while executing get_profile_size in the configuration script. This causes the locking for the dialog profiles never be released and Kamailio will stop serving traffic. Internal monitoring tools and RPC commands stay working, as long as they do not touch the dialog functionality. A similar (dedicated) Kamailio setup is used for tracking parallel channels for customers. Here the dead-lock is not observed that frequently, but aparentely also some crashes happens in a much longer time interval. ### Troubleshooting After analysis of the back-traces with GDB the get_profile_size() function was removed from the configuration script. After this change the crash did not happened anymore for several days. #### Reproduction Issue could not be reproduced so far. #### Debugging Data ##### bt 1 (some data removed) (gdb) bt \# 0 0x00007f57cf3b00da in get_profile_size (profile=0x7f50ccbc7e80, value=0x7ffd9928f300) at dlg_profile.c:859 n = 364 i = 12 ph = 0x7f50d3e4b7d0 \# 1 0x00007f57cf419c67 in w_get_profile_size_helper (msg=0x7f57d699d418, profile=0x7f50ccbc7e80, value=0x7ffd9928f300, spd=0x7f57d6916960) at dialog.c:941 \# 2 0x00007f57cf41a459 in w_get_profile_size3 (msg=0x7f57d699d418, profile=0x7f50ccbc7e80, value=0x7f57d6935118, result=0x7f57d6916960) at dialog.c:982 \# 3 0x0000000000463fea in do_action (h=0x7ffd99293610, a=0x7f57d6936488, msg=0x7f57d699d418) at core/action.c:1094 \# 4 0x00000000004711ee in run_actions (h=0x7ffd99293610, a=0x7f57d6936488, msg=0x7f57d699d418) at core/action.c:1581 \# 5 0x000000000046058b in do_action (h=0x7ffd99293610, a=0x7f57d690fda8, msg=0x7f57d699d418) at core/action.c:700 The first back-trace was taking from a running process with gdb.

[kamailio/kamailio] http_client leaks TLS shared memory (Issue #4231)
by Alexander Bakker 01 Apr '26

01 Apr '26

alexbakker created an issue (kamailio/kamailio#4231) ### Description Performing an HTTPS request using the ``http_client`` module results in a shared memory leak, seemingly related to TLS. ### Troubleshooting #### Reproduction Our use case for ``http_client`` is to update an htable with the latest banned IP's from APIBAN as described here: https://github.com/apiban/apiban?tab=readme-ov-file#integration-into-kamail…. Normally, we refresh the list of banned IP's once every 15 minutes, so the shared memory usage grows fairly slowly. The issue can be reproduced using the Kamailio configuration file below. To demonstrate the issue and make the shared memory usage grow faster, we set up a timer that calls ``http_client_query`` in a tight loop. To prevent unnecessary load on the APIBAN infrastructure, we request an example file from my personal server instead. ``` #!KAMAILIO debug=2 log_stderror=yes fork=yes enable_tls=1 loadmodule "tls.so" loadmodule "cfg_rpc.so" loadmodule "pv.so" loadmodule "xlog.so" loadmodule "ctl.so" loadmodule "rtimer.so" loadmodule "http_client.so" modparam("tls", "certificate", "") modparam("tls", "private_key", "") modparam("rtimer", "timer", "name=apiban;interval=100u;mode=1;") modparam("rtimer", "exec", "timer=apiban;route=APIBAN;") route[APIBAN] { xinfo("running apiban refresh\n"); http_client_query("https://alexbakker.me/u/7bvjn9jfas.txt", "$var(banned)"); } ``` Start Kamailio: ``` kamailio -f kamailio.cfg -DD ``` And then watch the shared memory usage grow rapidly: ``` watch -n1 -- kamcmd core.shmmem ``` #### Log Messages Eventually, Kamailio will run out of shared memory and print the following messages to the log: ``` 21(184184) INFO: <script>: running apiban refresh 21(184184) ERROR: http_client [functions.c:471]: curL_request_url(): failed to perform curl (56) (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) ERROR: http_client [functions.c:471]: curL_request_url(): failed to perform curl (56) (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) ERROR: <core> [core/mem/q_malloc.c:758]: qm_realloc(): qm_realloc(0x7585c73c4000, 1024) called from tls: tls_init.c: ser_realloc(372), module: tls; qm_malloc() failed! 21(184184) INFO: <script>: running apiban refresh 21(184184) INFO: <script>: running apiban refresh 21(184184) ERROR: <core> [core/mem/q_malloc.c:758]: qm_realloc(): qm_realloc(0x7585c73c4000, 1024) called from tls: tls_init.c: ser_realloc(372), module: tls; qm_malloc() failed! 21(184184) WARNING: http_client [functions.c:453]: curL_request_url(): TLS error in curl connection (url: https://alexbakker.me/u/7bvjn9jfas.txt) 21(184184) INFO: <script>: running apiban refresh 21(184184) INFO: <script>: running apiban refresh 21(184184) WARNING: http_client [functions.c:463]: curL_request_url(): TLS CA certificate read error (url: https://alexbakker.me/u/7bvjn9jfas.txt) ``` ``mem_dump_shm`` reports a large list of TLS-related allocations.

[kamailio/kamailio] cmake glitches (Issue #4317)
by Дилян Палаузов 25 Mar '26

25 Mar '26

dilyanpalauzov created an issue (kamailio/kamailio#4317) In the 6.0 branch the FLAVOUR option allows in cmake-gui (ccmake) setting `kamailio` as only option. As it is no-op, it should not be displayed in cmake-gui. The option MODULE_GROUP_NAME is documented as „Group of modules to build (one or multiple space seperated group)“. In cmake-gui it allows with enter to toggle between several values: DEFAULT, STANDARD, COMMON, KSTANDARD, KMINI, KPCRE, KMYSQL, KPOSTGRES, …. Using ccmake it is not possible to to set multiple values. The help string should mention all possible values. It should be plural: groups. The options in ccmake-gui `XSLT_VALIDATE,` and `XSLT_VERBOSE,` have a comma in their names too much. The option `CMAKE_BUILD_TYPE` allows in Kamailio toggling between four possible values: Debug, Release, MinSizeRel and RelWithDebInfo. ClamAV adds one more value for cmake-gui: `None`. This toggling is not yet available in the build system of cmake (when building cmake using cmake) - https://gitlab.kitware.com/cmake/cmake/-/issues/26434 . Is it reasonable to have for CMAKE_BUILD_TYPE also `None` as permitted value? I do not know the answer, that is why I am raising this question. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/4317 You are receiving this because you are subscribed to this thread.
