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.
>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.
Do you have any idea about this problem ?
Is this bug already known ?
Sincerely,
Nicolas LEROY
