Hi Andrei,
I'm Nicolas and I'm working with Adrien on crashes experienced on our
SER server during the last months.
We had 4 crashes on 11 jun 2009, 13 aug 2009, 11 sept 2009 and 12 sept
2009.
Every of this crash have a similar call flow, as seen in the one
attached: SER crashes when trying to process an ACK from the CPE for the
previously relayed "482 Loop Detected" from the gateway.
Yes, I saw the same thing.
From coredump analysis, the crash occures when
trying to match the ack
totag with a the out of bound local_totag from the
corresponding tm
entry (see attached coredump analysis)
It seems to me that there is a bug, and I didn't find any patch for
this, even in the last 2.0 versions.
Yes, it's a bug, but things changed a lot between versions.
It might be fixed even in 0.9.7.
Do you have any idea about this problem ?
No.
Is this bug already known ?
No.
If you can reproduce it easily, try it with 0.9.7 (it will work with the
same config as 0.9.4, you don't have to change anything).
If you can still see it, try compiling with debug support
(make proper; make mode=debug all and also don't forget to recompile
with mode=debug any other module you might be using that is not covered
by make all). After this the coredumps should be "better" (more info,
no variables will be optimized to registers).
Hopefully 0.9.7 will solve your problems. If it doesn't then send me again
some backtraces and/or the coredump + binaries (unfortunately the code
is very old and I'm not any longer familiar with it).
Andrei
