asterisk users - Jul 2016 - Impossible to use any recent asterisk version with chan_sip

Hello,
I'd like to know if anyone of you is finding my same problems using any
recent asterisk version, after 13.7 / 13.8  with chan_sip.

If I use any recent asterisk version, after just few seconds asterisk
completely locks up, stopping processing SIP/UDP packets. Nothing is
written in the asterisk log, but if I run "netstat -nap | grep 5060" I
see
the UDP buffer filled up.

If I step back to asterisk 13.2, then all is fine and asterisk is rock
solid.

I know I should use PJSIP and chan_sip is no more supported, but at this
point, if this is the working state of chan_sip, it should be completely
removed.

Leandro

It's not the normal working state of chan_sip, in fact it hasn't really 
been touched in any way that would cause this to happen and I haven't 
seen any bug reports along these lines. I also know that FreePBX is 
running both chan_sip and chan_pjsip and haven't experienced anything so 
it may be isolated to you. If you follow the instructions on the wiki[1] 
it will provide a backtrace which will show where chan_sip is hanging.

Joshua,

This was actually reported in
https://issues.asterisk.org/jira/browse/ASTERISK-25468 with backtraces. It
appeared to have started in 13.5, as I tested all from 13.2 to 13.6 at the
time

Hope this helps.

I've responded on the issue but the backtrace you've provided makes it 
appear as though the issue is actually in ODBC, which since chan_sip is 
using it in your deployment it causes it to lock up (why exactly is 
unknown).

Since it's separate you should create a new issue. If you don't want to 
I can do so tomorrow. The complete console output (with debug going to 
console in logger.conf and core set debug 3) as well as the 
configuration would also be useful.

Cheers,
