Next message: Ken Murchison: "RE: sync_client bails out after 3 MAILBOXES need upgrading to USER in one run"
I have read many threads regarding issues with deliver.db being in Berkeley
DB format. I am running cyrus-imapd-2.2.3-4 on Redhat AS3. I have not
had any issues with deliver.db until last week. I have about 200 accounts
with
most at 250MB, some at 500MB and a few at 1GB.
The issue started with messages as ...
relay=/var/lib/imap/socket/lmtp[/var/lib/imap/socket/lmtp], delay=40033,
status=deferred (conversation with
/var/lib/imap/socket/lmtp[/var/lib/imap/socket/lmtp] timed out while
sending end of data -- message may be sent more than once)

duplicate delivery database
A reboot did not fix the problem, but after I reconstructed the mailboxes
from a flatfile - it took 6 hours and then restarted everything, the issue
with lmtp refusing connections still existed. Oddly, the issue corrected
itself about a hour later?
I've read that stopping the server and simply removing the deliver.db and
tls_connections.db (in Berkeley format) and then restarting will result in
no harm. I also read that concverting a large Berkeley deliver.db(mine is
26MB) could take a long time ad result in a skiplist file of huge
proportions.
My question is - should I convert the deliver.db to skiplist? If I simply
move it elsewhere and change the imapd.conf to use a deliver.db in skiplist
and restart, what is lost? Surely this huge db contains information
necessary and useful to the message system?
Any illumination on this is appreciated.
