New subject: [Kamailio 4.2] Crash during burn-in test

8 Sep 2015

Hello,

the first frames of the backtrace don't have the symbol table, do have
other core files from where you can extract the bt full?

Also, 4.2.3 is old in its series, newer versions in branch 4.2 were
released. Can you update the latest version in branch 4.2 and reproduce
again? That will rule out is not a side effect of an issue fixed after
4.2.3. You don't need to change anything in config or database, just
grab the latest sources from branch 4.3 and install over the old binaries.

Cheers,
Daniel

 It can be reproduced not only once, steps like wrote before.

 Following link is the result of `bt full` from the core file generated:

 FYI

 Hello,

can you give the exact version: kamailio -v?

Also, the log message indicates that a core file was generated, sent the
backtrace taken from gdb:

gdb /path/to/kamailio /path/to/corefile
bt full

Could you reproduce the issue, or did it happen only once?

Cheers,
Daniel
