Hi

Have you checked if the checkpoint are really done.

I had that kind of problem twice and each time the ctl_cyrusdb -r take 
long because it was several days the checkpoint wasn't made.

I didn ' solve the problem but i never got it again.
I have made a script wich periodically check if the checkpoint is done.

If not the cyrus-imapd is restart the night after.
As the checkpoint is not made for less than a day it take less than an 
hour to restart.

I think this problem is not related to cyrus but moreover of the db3 
database.
It s kind of database corruption that prevet the checkpoint to be made.
