Very regularly...

...don't know how regularly before too long though...as I intend to move 
to Maildirs this next weekend.

It seems to happen regularly on an 80MB mbox accessing via Squirrelmail. 
  It doesn't surprise me much though, as UW would never do anything with 
teh boxes, but I figured with Dovecot's caching, etc., it might work 
better.  As I said though, I can access it via Thunderbird no problems. 
  Although, before with sqmail, it would just time out...whereas now 
with this larger mbox, it just craps out with that error.

I've also just seen a new error on a 33,000+ msg. mbox using 
Thunderbird, but it still retrieved the msgs. (after what looks like 
making another connection) and updated my mailbox on the client.

Here are the recent logs with both clients (I've labeled the 
Squirrelmail login squser and the Thunderbird login tbirduser).

Thanks for looking into it.  Hopefully it will make Dovecot even more 
solid before all is said and done.  I like it already though.  ;-)
