OpenSBC stopping automatically

Hi Joegen,

I am using version Unix Linux Version 1.1.5-85 of OSBC. I have problem because the pid is killed automatically after it has been up for almost 7 days. I can't see any log why this is happening. How can I check the logs for this?

Re: OpenSBC stopping automatically
One way is to check is if OpenSBC generated a core dump. If it did, use GDB to acquire a stack trace and send it here. I have recently commited a patch in CVS for a couple of crash scenarios.

Re: OpenSBC stopping automatically
what is GDB? How can I check if SBC generated a core dump? By the way this may be out of the topic but just wondering if we could connect SBC to asterisk as voicemail server? You may or may not answer my question just wondering.

Re: OpenSBC stopping automatically

Hi Joegen,

I don't know if this is what you need. Here is the result of generated core dump.

Using host libthread_db library "/lib/libthread_db.so.1".
Core was generated by `./opensbc -d -p ./pidfile -H 65536 -C 1024000'.
Program terminated with signal 3, Quit.
#0 0x00d9d402 in __kernel_vsyscall ()

Hi Oliver,

Yes that is what we need. However, you need to key in "bt" (backtrace) in the GDB interactive prompt so it woudl show the stack trace. Please resend whatever you get.

Hi Joegen,

Thank you very much. Here is the result of the back trace.

Re: OpenSBC stopping automatically
Seems like the core dump wasn't able to get the required debug symbols during the crash. It didn't say much. If you may, can you upgrade using version 101 and see if this crashing still occurs?
