[SR-Users] Kamailio Exits With: Segmentation Fault Error 4 in usrloc.so

Fri Feb 17 15:36:02 CET 2012

Hi,

I have Kamailio 3.2.2. I am using the raw_moni_capture_on of the sipcapture module.

Core was generated by `kamailio -w /home/core'.
Program terminated with signal 11, Segmentation fault.
#0  db_insert_ucontact (_c=0x7f5f8f737eb0) at ucontact.c:474
474                     vals[11].val.str_val = _c->sock->sock_str;

(gdb) p *_c
$1 = {domain = 0x7f5f8f72f590, aor = 0x7f5f918dfca8, c = {s = 0x7f5f8f737fb8 "sip:xxxxxxxxx at 192.168.5.125;transport=udp", len = 42}, received = {s = 0x0, 
    len = 0}, path = {s = 0x0, len = 0}, expires = 1329428753, q = -1, callid = {s = 0x7f5f8f738048 "e6f9144f80dd703b0995d19a168a54c1 at 192.168.5.125",

  next = 0x0, prev = 0x0}

(gdb) p *_c->sock
Cannot access memory at address 0x1
(gdb) 

Thanks,

Hello,

looks like an invalid listen socket structure, quite strange... what
    version of kamailio do you have?

Also, in gdb, frame 0, can you send the output of:

p *_c
p *_c->sock

You can replace sensitive data (like IP), if you wish.

Cheers,
Daniel
