Hi Markus,
I'm not 100% sure the crash is caused by NULL callid in the db table.
SER is able to skip this kind on error on load an you will get something
like:
0(0) preload_udomain: ERRROR: bad callid record in table voicemail
0(0) preload_udomain: ERRROR: for username user1, contact sip:contact at ip
0(0) preload_udomain: ERRROR: skipping...
see modules/usrloc/udomain.c function preload_udomain()
the bet way to make some light is to generate a core when ser crashes
and to look at the backtrace.
to enable coredump, be sure to do "ulimit -c ulimited" set before
running ser.
regards,
Marian
