[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] 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. The counter in f0 does not increased that much during this time, probably due the overflow of the loop counter. ##### bt2 (analysis with data structure with gdb scripts) Here the loop counter in f0 showed a really high value. Expected size of dialog profiles hash table: (gdb) p profile->entries[3] $4 = {first = 0x7f9bfd4aad98, content = 2068} (gdb) p profile->entries[7] $3 = {first = 0x7f9c12079f70, content = 784} (gdb) p profile->entries[12] $6 = {first = 0x7f9c02be5d50, content = 7600} (gdb) p profile->entries[14] $2 = {first = 0x7f9bff636de8, content = 6764} hash table bucket 14 shows a lot of corruption and the loop never ends (carrier names and IPs replaced).

[kamailio/kamailio] Writing to $fU or $tU appends to header user (Issue #3165)
by Benoît Panizzon 24 Jun '25

24 Jun '25

Dear Gang Possibly @oej could provide more in-depth information as he has witnessed this issue. Usually the user of the from URI is the phone number displayed at the destination. There are situations where this phone number is translated. As example. In Switzerland, the user is used to see numbers in a local format. National number starting with 0 and international numbers with 00 but on interconnection between telcos, e164 is used. So basically when a call is sent to a customer '+41' is replaced by '0' and '+' is replaced by '00'. Let's start with an example From: header: `From: "Maurice Moss" <sip:+41991234567@example.com>;user=phone` So shortly before the call is sent out to the location of the registered CPE, this is done: ``` if ($fU =~ "^\+41") { $fU = "0" + $(fU{s.substr,3,0}); } else if ($fU = ~ "^\+") { $fU = "00" + $(fU{s.substr,1,0}); } ``` What is sent to the CPE now looks like this: `From: "Maurice Moss" <sip:0991234567@example.com>;user=phone` Now we hit an error like 486 BUSY and the destination has call forwarding active to a mobile phone on another TSP. So we have to send the call out back the IC and numbers need to be translated back to e164. We handle this in a failure route, which in turn could trigger a branch route. So we revert the number back to e164: `$fU = "+41" + $(fU{s.substr,1,0});` Expected outcome: `From: "Maurice Moss" <sip:+41991234567@example.com>;user=phone` Observed outcome: `From: "Maurice Moss" <sip:0991234567+41991234567@example.com>;user=phone` So setting $fU more than once is appending to the user element of the From header URI. This behavior has not been found in any documentation. I have been working around most of the issues by making sure I change $fU (and $tU) at the latest possible time and only once. But in the case described above, I have not been able to come up with a work-around yet. I also can't think of any benefit of the way those PV are handled or any harm that could be done, to handle them differently and make the last 'write' overwrite and previous value, instead of appending. Thank you for looking into this. -Benoît- -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3165 You are receiving this because you are subscribed to this thread.
