[sr-dev] SER crash : Segmentation fault

Fri Sep 11 19:01:34 CEST 2009

Hi Andrei,

A new crash happend today !

It was impossible to restart SER. During this time I could collect logs
from syslog by activating ser debug (ie. facility local0, etc.).

The solution have consisted in flushing Location table to be able to
restart SER...

I attach the gdb output and syslog trace to this email. Do you see that
the problem is same as the previous one ?

Regards,

Adrien
