Hello,

looks like a buffer overflow by 1 byte. Are you using any custom module/additional patches, or is it stock kamailio?

Cheers,
Daniel

Hello!

 

I'm facing an issue 2/3 times a day with the following errors in the logs:

Nov 22 00:09:02 /usr/local/sbin/kamailio[3720]: CRITICAL: <core> [core/mem/q_malloc.c:150]: qm_debug_check_frag(): BUG: qm: prev. fragm. tail overwritten(c0c0c000, abcdefed)[0x7f9600b754f8:0x7f9600b75530]! Memory allocator was called from core: core/re.c:430. Fragment marked by core: db_res.c:139. Exec from core/mem/q_malloc.c:391.

Nov 22 00:09:02 /usr/local/sbin/kamailio[3720]: CRITICAL: <core> [core/mem/q_malloc.c:155]: qm_debug_check_frag(): BUG: qm: prev. fragm. tail overwritten [0x7f9600b75460:0x7f9600b75498] - fragment marked by tm: t_fwd.c:230

Nov 22 00:09:02 abrt-hook-ccpp: Process 3720 (kamailio) of user 0 killed by SIGABRT - ignoring (repeated crash)

 

Do you have any idea where it could come from? I'm running Kamailio 5.6.4.

 

Regards,

 

Igor.
