Postgres: Exclusive Transaction Locks vs. Vacuumer
by Stefan Kohlhauser 21 Oct '16

21 Oct '16

Hey everyone! We noticed that under high load of registrations and using the pua module we can reach a state where the PUA table bloats our Postgres to several GB. However, a SELECT on pua only shows a few hundred entries. The other half million or so entries are obsoleted but not cleaned up. The reason for this seems to be that the autovacuumer of the Postgres can't get to work because the PUA table is almost permanently locked. Our Postgres logs are full with errors about the autovacuumer being canceled because it couldn't get to work. Looking at modules/db_postgres/km_dbase.c::db_postgres_start_transaction() I noticed that there are two locking modes used: str lock_write_end_str = str_init(" IN EXCLUSIVE MODE"); str lock_full_end_str = str_init(" IN ACCESS EXCLUSIVE MODE"); According to https://www.postgresql.org/docs/9.2/static/explicit-locking.html these modes mean forbidding everything else except reads and forbidding everything else. However, according to this documentation ROW EXCLUSIVE is the standard lock for entry altering operations (INSERT, UPDATE, DELETE). And this would still allow the autovacuumer to do its job. Is there a specific reason why these more restricting locking modes are used instead of ROW EXCLUSIVE? Thanks. Best regards, Stefan

TCP FIN after 10 minutes
by gmele 20 Oct '16

20 Oct '16

Hello, we have deployed a Kamailio acting as SIP proxy on a RHEL 7.2 machine. Clients (mainly mobile phones) connects to the proxy using a TLS protected TCP connection. In the kamailio config, we've set : #!ifdef WITH_TLS enable_tls=yes tcp_async=yes tcp_connection_lifetime=3605 tcp_accept_no_cl=yes tcp_crlf_ping = yes #!endif Our problem is that, even if we set the tcp_connection_lifetime to > 1 hour, the tcp connection is closed after 10 minutes: on tcp dumps, we see clearly the TCP FIN sent by machine hosting the kamailio proxy... Setting parameters tcp_keepidle/keepintlv/keepcnt in the kamailio config didn't change the behavior. We also set TCP keepalived at system level, but without result... This TCP closure is causing us lot of problems when calls between 2 UAs last more than 10 minutes because the REINVITE or BYE messages are lost. Also, closing the TCP connection will wake up the mobile app and make it resend a REGISTER, thing we absolutely want to avoid. Is there a parameter we can use to avoid this closure? I had a look in previous posts, found people with the same problem as mine, but no real solution... Thx for your help.

sipml5 fail invite kamailio ims web sockets
by Serhat Guler 20 Oct '16

20 Oct '16

Dear all, I can register the sipml5 client to my kamailio IMS setup successfully, but when I try to make a call the invite fails with "478 Unresolvable destination". From the wireshark trace file I think the PCSCF on the terminating side cannot resolve the destination. After the invite request fails the caller re-registers to the networkj automatically. The wireshark file is attached. The registration process happens successfully but all of the nodes give some errors: 10(3773) INFO: <script>: [REGISTER] from [sip:alice@net1.test] to [sip:alice@net1.test] 10(3773) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=425 a=25 n=xlog 10(3773) ERROR: <script>: REGISTER (sip:alice@net1.test (192.168.0.10:14115) to sip:alice@net1.test, 25c80750-d52d-30c8-d373-c0136401a927) 10(3773) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=437 a=16 n=if 10(3773) ERROR: *** cfgtrace:request_route=[DEFAULT_ROUTE] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=437 a=5 n=route 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=627 a=16 n=if 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=622 a=25 n=mf_process_maxfwd_header 10(3773) DEBUG: <core> [parser/msg_parser.c:153]: get_hdr_field(): get_hdr_field: cseq <CSeq>: <59840> <REGISTER> 10(3773) DEBUG: <core> [parser/msg_parser.c:187]: get_hdr_field(): DEBUG: get_hdr_body : content_length=0 10(3773) DEBUG: maxfwd [mf_funcs.c:85]: is_maxfwd_present(): value = 70 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=633 a=16 n=if 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=627 a=26 n=sanity_check 10(3773) DEBUG: <core> [parser/msg_parser.c:89]: get_hdr_field(): found end of header 10(3773) DEBUG: sanity [mod_sanity.c:248]: w_sanity_check(): sanity checks result: 1 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=639 a=16 n=if 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=633 a=24 n=has_totag 10(3773) DEBUG: siputils [checks.c:97]: has_totag(): no totag 10(3773) DEBUG: <core> [select.c:412]: run_select(): Calling SELECT 0xb6e5fe40 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=645 a=16 n=if 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=639 a=25 n=is_method 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=649 a=16 n=if 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=645 a=24 n=t_lookup_request 10(3773) DEBUG: tm [t_lookup.c:1011]: t_check_msg(): DEBUG: t_check_msg: msg id=2 global id=1 T start=0xffffffff 10(3773) DEBUG: tm [t_lookup.c:466]: t_lookup_request(): t_lookup_request: start searching: hash=21728, isACK=0 10(3773) DEBUG: tm [t_lookup.c:424]: matching_3261(): DEBUG: RFC3261 transaction matching failed 10(3773) DEBUG: tm [t_lookup.c:648]: t_lookup_request(): DEBUG: t_lookup_request: no transaction found 10(3773) DEBUG: tm [t_lookup.c:1080]: t_check_msg(): DEBUG: t_check_msg: msg id=2 global id=2 T end=(nil) 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=652 a=16 n=if 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=649 a=25 n=is_method 10(3773) ERROR: *** cfgtrace:request_route=[REQINIT] c=[/usr/local/etc/kamailio/kamailio-pcscf.cfg] l=650 a=26 n=send_reply 10(3773) DEBUG: sl [sl.c:280]: send_reply(): reply in stateless mode (sl) 10(3773) DEBUG: websocket [ws_conn.c:429]: wsconn_get(): wsconn_get for id [2] 10(3773) DEBUG: websocket [ws_conn.c:437]: wsconn_get(): wsconn_get returns wsc [0xb2329228] refcnt [2] 10(3773) DEBUG: websocket [ws_frame.c:751]: ws_frame_transmit(): Tx message: The SCSCF says (while inviting): 0(3582) ERROR: dialog_ng [dlg_handlers.c:196]: populate_leg_info(): bad sip message or missing Contact hdr 0(3582) ERROR: dialog_ng [dlg_handlers.c:453]: dlg_onreply(): could not add further info to the dlg out Making calls between 2 IMS clients(boghe) is possible.

Kamailio script config - Generate Documentation
by José Seabra 20 Oct '16

20 Oct '16

Hello there, I'm sending this email in order to know if anyone had work or has any idea how we can generate Documentation from kamailio script using Comments? This would be great because we could write comments explaining the Route method during script development and use it to generate documentation about our kamailio script, saving time and leave our deployment documented. Thank you -- Best Regards José Seabra

memory is not freed in system, while kamailio's statistic shows OK
by Vasiliy Ganchev 20 Oct '16

20 Oct '16

Hi folk! Have a production server - used as webrtc to sip proxy - it is built on kamailio v 4.4.2 - Server handles connections from ~4000 incoming SIP trunks (transport=TLS). Kamailio provides auth for this trunks. - Kamailio receives also connections from Webrtc app. Calls from Webrtc routed to one of the 4000 sip trunks. Server is running on Debian GNU/Linux 7 The number of calls on the system is small. Most of the load is generated by registration/re-registrations of SIP trunks The problem is following: - output of kamcmd core.shmmem and kamcmd pkg.stats shows constant using of memory - output of htop shows constantly increasing memory usage, e.g. after one week working: PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command ..... 6013 kamailio 20 0 744M 134M 130M S 0.0 3.6 2:28.80 /usr/sbin/kamailio -f /etc/kamailio/kamailio.cfg -P /var/run/kamailio/kamailio.pid -m 512 -M 32 -u kamailio -g kamailio 6002 kamailio 20 0 744M 134M 130M S 0.0 3.6 2:30.93 /usr/sbin/kamailio -f /etc/kamailio/kamailio.cfg -P /var/run/kamailio/kamailio.pid -m 512 -M 32 -u kamailio -g kamailio 6012 kamailio 20 0 744M 134M 130M S 0.0 3.5 2:35.00 /usr/sbin/kamailio -f /etc/kamailio/kamailio.cfg -P /var/run/kamailio/kamailio.pid -m 512 -M 32 -u kamailio -g kamailio 5991 kamailio 20 0 744M 133M 129M S 0.0 3.5 2:05.88 /usr/sbin/kamailio -f /etc/kamailio/kamailio.cfg -P /var/run/kamailio/kamailio.pid -m 512 -M 32 -u kamailio -g kamailio 6018 kamailio 20 0 744M 133M 129M S 0.0 3.5 2:31.90 /usr/sbin/kamailio -f /etc/kamailio/kamailio.cfg -P /var/run/kamailio/kamailio.pid -m 512 -M 32 -u kamailio -g kamailio .....

Active calls limit
by Ivan Dudko 19 Oct '16

19 Oct '16

Hello! I am trying to implement limit of active calls for subscribers. And for each subscriber this limit must be personal. I find example route in presentation of Daniel-Constantin Mierla. And i need to set $xavp(caller=>active_calls) = 1; for each dialog. But i can't understand how to load this number of active calls from some-thing similar of user profile or subscriber table? route[DIALOG] { if (is_method("CANCEL") || (has_totag() && is_method("INVITE|BYE|ACK"))) { dlg_manage(); return; } if (is_method("INVITE") && !has_totag() && !isflagset(WITH_ACTIVE_CALLS_LIMIT)) { if( $xavp(caller[0]=>active_calls) != $null && $xavp(caller[0]=>active_calls) > 0 ) { if(!get_profile_size("caller", "$fU@$fd", "$var(acsize)")) { send_reply("500", "No more active calls"); exit; } if($var(acsize)>=$xavp(caller[0]=>active_calls)) { send_reply("403", "No more active calls"); exit; } set_dlg_profile("caller", "$fU@$fd"); } setflag(WITH_ACTIVE_CALLS_LIMIT); dlg_manage(); } }
