If you don't have the mask ip to your host ip (kamailio listening ip) like Alex pointed, do you have a core dump from where you can send the backtrace?

Cheers,

Hi Alex/Daniel,

so THe IP of this SIP proxy is x.x.x.11 and I am using x.x.x.10 for the Mask IP.

I see the coredump in the root of the server..

ls /core -lah

-rw------- 1 root root 134M 2010-11-20 19:48 /core

which is the date it crashed.

gdb /sbin/kamailio /core

This GDB was configured as "i486-linux-gnu"...

Cannot access memory at address 0xb75f3fb0

I am running gdb from debian repo on 5.04 maybe I need to compile gdb?

Hello,

No, the problem is with the coredump AFAIK. Try looking thru /var/log/messages and dmesg for any indication of a coredump and the module that generated it. Please email those lines as well.

Hello
I see that the interesting line is already in the first mail . Please try this

readelf -S /path/to/topoh.so

You should have somethink like this

[Nr] Name              Type            Addr     Off    Size   ES Flg Lk Inf Al
[ 0]                   NULL            00000000 000000 000000 00      0   0 0
.....
[10] .init             PROGBITS        00001914 001914 000030 00 AX 0   0 4
[11] .plt              PROGBITS        00001944 001944 000430 04 AX 0   0 4
[12] .text             PROGBITS        00001d80 001d80 008008 00 AX 0   0 16

Note the address of the .text segment (in my case is 0x00001d80)

Then

gdb /path/to/kamailio core.dump

in the gdb console load the topoh.so

add-symbol-file /path/to/topoh.so 0xb7004000 + 0x<offset of .text segment found as above>

then check the value of the Instruction pointer IP (0xb70070d9) Still in the gdb console

x/s 0xb70070d9

You will get an offset relative to a function where the crashed happened. This would be very helpful so please share the finding. Also do a info registers (in the gdb console) and paste the content of the registers as well.
