[JDEV] jabber dumping core at random(?)

[Benjamin Ritcey]

Hello all,

For the last two days, I've come in to find our Jabber server has dumped 
core.  I've been running for about two weeks with no problems and I am 
not aware of any recent changes.

Here's a backtrace:

This GDB was configured as "i386-redhat-linux"...
Core was generated by `jabberd/jabberd'.
Program terminated with signal 11, Segmentation fault.

The last thing in error.log was:

20011024T09:42:35: [notice] (update.jabber.com): bouncing a packet to 
959967024 at update.jabber.com/1.10.0.6 from 
user at jabberbox.ritcey.com/Jabber Instant Messenger: Unable to deliver, 
destination unknown

which corresponds to the time of the core file.

I'm running jabber 1.4.1 w/ xdb_sql 1.1 (plus fixes).

Any ideas?  Any other info needed?

Thanks much,
