I wrote a script to reconstruct any mailbox that showed corruption 
during cyr_expire. I had to reconstruct about 4000 accounts the first 
week and another 5000 or so the second week. It has been well over two 
weeks now since any further corruption.

The only thing I can think of is that these mailboxes have been 
"corrupt" for quite a while (years maybe) but they only started showing 
problems once we enabled delayed expunge/delete .
