I seem to have more success reproducing this problem if I delete and
expunge messages before immediately injecting messages through LMTP by
using a small script on the MTA.
I can not say for sure if this is isolated to LMTP.

I have rebuilt the IMAP server without the INTERNALDATE patch from
fastmail and I am still having this problem.

I know this is a very high level description of the problem. The logs
describing the problem that I attached to my original post is the best
I can do. Can anyone suggest how I can examine this problem more
closely?
