ctl_deliver not finishing

[Brandon High]

I'm having a bit of a problem on our IMAP server. There are several
instances of ctl_deliver, some running for over 2 days.

# ps -ef|grep deliver
   cyrus   331   303 27   Jan 29 ?       2671:33 ctl_deliver -E 3
   cyrus  6736   303 26 12:48:32 ?       112:04 ctl_deliver -E 3
   cyrus  2647   303 27   Jan 30 ?       1281:16 ctl_deliver -E 3

Looking at /var/adm/messages, process 331 generated the following error:
Jan 29 12:48:40 ix ctl_deliver[331]: DBERROR db4: DB_ENV->log_flush: LSN past current end-of-log

The system is Solaris 5.7, cyrus-imapd-2.1.5, cyrus-sasl-2.1.5,
db-4.0.14

Any idea on recovering the problem gracefully? What might be causing it,
and any fixes?

Thanks
-B
