Hello,
looks like the issue is in the way shut down is done. In this specific
case, sqlops does not initialize properly due to misspell, causing
kamailio to shut down -- otherwise there is no issue with sqlops itself.
At shutdown, the destroy function of each module is called, then the
module structure is freed. Looks like mysql module is destroyed first,
then htable module is destroyed, which needs to connect to sync back the
content in memory to db tables, but the mod exports structure for mysql
is invalid now causing a fault access.
I will make a patch for it.
Cheers,
Daniel

Hello,
I pushed a commit on the master that tries to make a graceful shutdown:
http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=2396dde…
Maybe you can try it with your case again and see if all goes fine now,
then it can be backported.
Thanks,
Daniel

daniel,
i tried with latest master and my sip proxy didn't crash anymore at
startup, when sql_query connection argument was misspelled.
