I'm getting strange timeouts occasionally on Dovecot 1.0.rc15 on Debian 4.0, and haven't been able to figure out the cause.

Eventually, I get:

I've tried enabling all the debugging, but there don't seem to be any errors.

Any ideas?

Thanks, Brandon Upgrade. rc15 way over a year old. I think backports has newer version.
