Re: [sr-dev] kamailio 4.0.3 crash

Hi Here is the output: gdb)  (gdb) frame 0 #0  qm_detach_free (qm=0x7fd96175e010, size=112) at mem/q_malloc.c:266 266in mem/q_malloc.c (gdb)  #0  qm_detach_free (qm=0x7fd96175e010, size=112) at mem/q_malloc.c:266 266in mem/q_malloc.c (gdb) p *frag $1 = {size = 7599108840079127868, u = {nxt_free = 0x3965663931343a64, is_free = 4135824228634344036}} (gdb)  $2 = {size = 7599108840079127868, u = {nxt_free = 0x3965663931343a64, is_free = 4135824228634344036}} (gdb)  $3 = {size = 7599108840079127868, u = {nxt_free = 0x3965663931343a64, is_free = 4135824228634344036}} (gdb) p *((char*)frag + sizeof(struct qm_frag)) $4 = 99 'c' Is it okay to run with MEMDBG=1 in production ? Wouldn't it make it a little slow ? Just let me know if u want so see something else with gdb. Unfortunally  I do not have SIP traces, but I have the core file and some logs.

You should update to latest git branch 4.0, because there were some other fixes from 4.0.3. With this occasion, you should set MEMDBG=1 in Makefile.defs before recompiling the new version to be able to catch easier the overwrites of memory.
