The db transaction logs have some number of unclosed transactions, so what 
ends up happening is ctl_cyrusdb reopens the same file again and again... 
and never closes it after the transactions are replayed. I talked to our 
local DB expert, and he suggested something I need to test yet which will 
make this not happen in the future, but in the meantime, you either get to 
delete the transaction logs and reupdate your mailboxes database from 
server state, increase the file descriptor limit on ctl_cyrusdb, or hack 
your bdb library to reuse a file descriptor or close it after every 
transaction.
