LMTP Timeout

[Phil Chambers]

This is an update on progress with diagnosing my problem with LMTP/IMAP hanging.

My diagnosis with reconstruct was a red herring!  While I was patching 
reconstruct to give diagnostics Exim tried a delivery and lmtpd locked the 
user's cyrus.header file before hanging. When I killed the lmptd proces I found 
no problem with reconstruct.

So, back to square one.  I can't think of a way to debug this. It is imapd and 
lmtpd which are hanging and I cannot possibly put diagnostic code into those 
because the logs would explode on a live system.

I really need some suggestions!

Phil.
