For what it's worth, we've been doing a reconstruct on the entire 
mailstore every night for the better part of a year, without ever 
shutting down cyrus.  The reason is that we do a Trend Micro scan of the 
mailstore nightly - a couple of times a month that catches a virus which 
wasn't caught as the mail arrived (probably because of updated virus 
definitions).  Anyway, whenever Trend quarantines a message then that 
folder is corrupted, and the reconstruct fixes that.  Hasn't caused 

That doesn't mean it's the smart thing to do, of course...

Cyrus is running on Fedora Core 3 linux.  Mailstore is 17Gb.
