Try to attach gdb to the kamailio processes and run a full backtrace.

Hi,
In the mean time we have gathered more information on this problem:
As given below, kamailio stops grabbing UDP SIP messages (SIP registrations)
after running a while on an embedded ARM and PPC platform (which runs linux
2.6.33 kernel). Some times the hangup occures within hours and some times
after couple of days running.
NETSTAT OUTPUT:
root# netstat -pl | grep kam
udp 1047968 0 (null):sip (null):*
8416/kamailio
raw 0 0 (null):255 (null):* 255
8416/kamailio
unix 2 [ ACC ] STREAM LISTENING 755205 8429/kamailio
/tmp/kamailio_ctl
Kamailio is started with the following options = -m 4 -n 3 -f <cfg> -D
Other relevant info:
- When Kamailio hangs, I also noticed that the flag "inuse_transactions" has
always the value of '1'. Readout with "kamctl monitor".
- A simple cat to /proc/<kamailio_pid>/wchan gives us the function:
futex_wait_queue_me.
- All possible polling methods are used with -W parameter (sigio_rt, poll,
select etc) during these tests. Non of these options did solve this problem.
I hope the additional info will clarify more. Thanks in advance.
Best regards,
Orhan Yilmaz

In a previous e-mail, you posted a warning that you had while compiling:
"no native memory barrier implementations, falling back to slow lock
based workarround"
which means that you are already running without atomic locks.

Hi,
Here's an update of this topic. We've tried again with the latest stable
version 4.0.4. Unfortunately the problem still exists.
In mails above it is mentioned to use kamailio without atomic locks. How
do
we this (e.g. which makefile options)?
Kind regards,
Bert

4.0 (current trunk) is in code freeze. I would suggest to test the
trunk version (next 4.0).
Even openser 1.3 requires patches to be properly cross compiled.

Hi Ovidiu,
Thanks for the warning! We did not yet have much success running the
current master branch, though this may well be a resource problem on
the target platform.
For the moment, we decided to switch back to openser 1.3.5 and wait
for the official 4.0 release.
