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.

Your opensips is still not compiled with mem debugging :(...The dump from
memory debugger looks like:
0(17665) Memory status (shm):
0(17665) qm_status (0xb5a7e000):
0(17665) heap size= 33554432
0(17665) used= 1592952, used+overhead=1811564, free=31742868
0(17665) max used (+overhead)= 1811564
0(17665) dumping all alloc'ed. fragments:
0(17665) 0. N address=0xb5ab240c frag=0xb5ab23f4 size=4
used=1
0(17665) alloc'd from mem/shm_mem.c:
shm_mem_init_mallocs(199)
0(17665) start check=f0f0f0f0, end check= c0c0c0c0, abcdefed
0(17665) 1. N address=0xb5ab2440 frag=0xb5ab2428 size=4 used=1
0(17665) alloc'd from timer.c: init_timer(52)
0(17665) start check=f0f0f0f0, end check= c0c0c0c0, abcdefed
Just to check the flags you use, please upload your Makefile.defs and post
the output of "opensips -V" .
Thanks and regards,
Bogdan

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
