I'm running two instances of GWIA (GW8.01HP1) on SLES10SP3(64bit) (no OES). I have a secondary domain on this box for my SMTP server (GWIA instance1, port 25) and then on that same domain, I'm running a second GWIA instance with IMAP (port 110) and SMTP (port 465) over TLS. This ran fine for about six months in this configuration and I haven't made any changes to the system.

Recently in the last month or so the second (IMAP) instance of GWIA started crashing periodically with the following dump to console. When I restart it, it will run fine for a few days to a few weeks, then crash again. The other instance of GWIA keeps humming right along through this though. I searched around but didn't see any known issues similar to this.

Could this be a DB issue that a rebuild might fix?
