app_python3 crash woes
by Alex Balashov 22 Sep '22

22 Sep '22

Hi, Some exceptions generated in Python script cause a harmless traceback in the logs, while others cause Kamailio to crash: Sep 22 06:28:34 proxy /usr/sbin/kamailio[3984]: CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 11 Sep 22 06:28:34 proxy /usr/sbin/kamailio[3957]: ALERT: <core> [main.c:783]: handle_sigs(): child process 3965 exited by a signal 11 Sep 22 06:28:34 proxy /usr/sbin/kamailio[3957]: ALERT: <core> [main.c:786]: handle_sigs(): core was generated (gdb) where #0 0x00007fdaea729079 in vfprintf () from /lib64/libc.so.6 #1 0x00007fdaea754179 in vsnprintf () from /lib64/libc.so.6 #2 0x00007fdac45e9afd in make_message () from /usr/lib64/kamailio/modules/app_python3.so #3 0x00007fdac45e5bc9 in python_handle_exception () from /usr/lib64/kamailio/modules/app_python3.so #4 0x00007fdac45ebfde in apy_exec () from /usr/lib64/kamailio/modules/app_python3.so #5 0x00007fdac45ecef1 in python_exec2 () from /usr/lib64/kamailio/modules/app_python3.so #6 0x0000000000474ee0 in do_action () #7 0x000000000048217d in run_actions () #8 0x0000000000474d39 in do_action () #9 0x000000000048217d in run_actions () #10 0x0000000000474d39 in do_action () #11 0x000000000048217d in run_actions () #12 0x0000000000474d87 in do_action () #13 0x000000000048217d in run_actions () #14 0x00000000004828c1 in run_top_route () #15 0x00000000005e8044 in receive_msg () #16 0x00000000004df772 in udp_rcv_loop () #17 0x0000000000429f5b in main_loop () #18 0x000000000043423e in main () Is there a reasonable way to try to prevent this type of mid-air explosion? — Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Substdef syntax change?
by Fredrik Dahlgren 20 Sep '22

20 Sep '22

Hi, I'm looking at a kamailio config where all substdef have the syntax "!regexp!subst!flags", "!DB_URL!db.example.com!g" but i can't find this syntax in the documentation. It's currently running on a fairly modern 5.x version and as far as i know it has never been on 4.x or older. Does anyone know where this syntax is from and if it's possible/recommended to simply replace it with "/regexp/subst"? *Fredrik* *Dahlgren* | Senior SIP/VoIP Engineer fredrik.dahlgren(a)freespee.com | LinkedIn <https://www.linkedin.com/company/freespee/> | Twitter <https://twitter.com/freespee>

Kamailio stops processing requests mid script
by Joel Serrano 20 Sep '22

20 Sep '22

Hello, I have a cluster of 2 kamailios v5.5 on debian 9 working flawlessly. We have added a third node, also on v5.5 but debian 11. Kamailio doesn't work correctly for some reason that I'm not seeing. The symptoms are: 1- Kamailio receives INVITEs and starts to process them per routing script. 2- There is a specific place where something happens and the calls are dropped (Kamailio is not even replying to the source). Note that the config is exactly the same on all 3 servers, only one of the three is having the issue. I enabled debug logs and I could see: [...] Sep 10 12:30:48 sbc03 sbc[956340]: exec: {1 102 INVITE 5111a7c71ec485e443099844491ef7d8(a)sip02.example.com} *** cfgtrace:dbg_cfg_trace():

Kamailio v5.5.5 Released
by Daniel-Constantin Mierla 19 Sep '22

19 Sep '22

Hello, Kamailio SIP Server v5.5.5 stable release is out. This is a maintenance release of the stable branch 5.5 that includes fixes since the release of v5.5.4. There is no change to database schema or configuration language structure that you have to do on previous installations of v5.5.x. Deployments running previous v5.5.x versions are strongly recommended to be upgraded to v5.5.5. Note that 5.5 is the second last stable branch, still officially maintained by Kamailio development team. The latest stable branch is 5.6, with v5.6.1 being release out of it. For more details about version 5.5.5 (including links and guidelines to download the tarball or from GIT repository), visit: * https://www.kamailio.org/w/2022/09/kamailio-v5-5-5-released/ RPM, Debian/Ubuntu packages will be available soon as well.

Releasing Kamailio v5.5.5
by Daniel-Constantin Mierla 19 Sep '22

19 Sep '22

Hello, I am considering to release Kamailio v5.5.5 soon, likely on Monday or Tuesday next week (Sep 19 or 20, 2022). This is the usual heads up notification to see if anyone is aware of issues not yet reported to bug tracker and if yes, do it as soon as possible to give them a chance to be fixed.

Log levels severely impacts performance
by Amit 16 Sep '22

16 Sep '22

Hello, We’ve been running Kamailio 5.5.0 for a while now and recently ran into an issue where the application buffer would get full and Kamailio has a lot of difficulty keeping up with REG requests. This severely impacted Kamailio’s ability to perform and resulted in many REG timeouts. Running ‘watch netstat -ulpn’ revealed the buffer issue. We usually run the production system at log level INFO (2) and had not ran into any issues in the past. When the buffer issue occurred and after some testing, we discovered that changing the log level to NOTICE (1) was sufficient to bring the system back into operational status. For example, at log level INFO (2) we seem to achieve ~150-200 REG/s while at log level NOTICE (1) we reach ~500-700 REG/s. I did find this article in the wiki and tried using the “-“ in front of the log path but this didn’t seem to help. http://www.kamailio.org/wiki/tutorials/3.2.x/syslog Even writing the logs directly to our external log server and preventing them from being written to the local disk doesn’t seem to alleviate the issue when the log level is set to INFO (2). Does anyone have any experience with this or have any suggestions? We are finding it difficult to scale as a result of this issue. Thank you in advance. Amit

TM Module, avp not present during handling of ack, prack and cancel?
by Benoît Panizzon 16 Sep '22

16 Sep '22

Hi List If I'm correctly reading the documentation, all avp variables should exist during a transaction until it's final ACK. ACK, PRACK and CANCEL are part of that transaction. But I seem not to be able to access the content of avp during those messages. Strangely during MANAGE_REPLY of the 487 following a cancel, the avp are present so that 487 clearly is part of the transaction. What am I missing? (Yes, I am still working on mirroring al username (phone number) translations and filtering unwanted header to prevent information leakage, any hints welcome if there is a simpler way to achieve this) -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________
