DB Errors

sure if the first one went)

Greetings.  For about 2 months now I have been having a lot of problems 
with my Cyrus delivery system.  I keep getting DB errors of various 
types. Sometimes I get region size errors, other times full corruption, 
and a few others.  I have tried deleting deliver.db, tls_sessions.db, 
the db directory, all together, etc.  When I do so the errors stop for 
maybe 3 days and then start again.  Usually in the morning when I come 
in I am getting the errors, but occasionally it happens in the middle 
of the day.  Here is what I am currently running.

YDL 4.0 (This started a month or two after upgrading to YDL 4.0, can't 
say if it is related)
cyrus-imapd 2.2.10 (release 3.yd4)
cyrus-sasl 2.1.18 (release 2.2)
db4 4.2.52 (release 3.1.ydl.1)
compat-db 4.1.25 (release 2.1)

If there is any other information I can give, please let me know.  The 
situation is getting bad, we are having to "service cyrus-imapd 
restart" almost every morning (doing so fixes the problem until the 
next morningish time).
