Summary: mem leak
Initial Comment:
Errors in the syslog this time right before the crash:
/usr/local/sbin/opensips[27044]: ERROR:db_flatstore:new_flat_id: no pkg memory left
kernel: [5508366.582447] opensips[27044]: segfault at 10 ip 7fa7ff74c21f sp 7fffdc101700 error 4 in db_flatstore.so[7fa7ff749000+5000]
I do use the flat_rotate MI command with the acc module for cdr collection. The backtrace is attached.

Message:
a shutdown dump is not relevant - try to make a runtime dump by sending
SIGUSR1 signal to opensips - wait for couple of hours of run and make the
dump.
Thanks and regards,

Is this a runtime dump or a shutdown one ?

Hi,
Indeed, the logs show a leak and I suspect it is from db_flatstore module
- unfortunately you do not have properly compiled the memory debugging
support, so it hard to pinpoint the guilty code.
I tried to reproduce ACC via flatstore, but not able to get a leak at
all...
So, please compile the memory debugger as per
http://www.opensips.org/Resources/DocsTsMem (be sure you put DBG_QM_MALLOC
and take out F_MALLOC ) and recompile + reinstall + restart opensips.
In your cfg use:
memlog=10
memdump=1
This will generate only a memory dump without any additional memory logs
at rutime.
You can take a mem dump at runtime by sending a SIGUSR1 signal to an
opensips process,
Regards,
Bogdan
