Hi guys,

My UW IMAP server seems to be struggling to deal with the above
command. It simply dies when trying to run it. What is strange is that
it ONLY affects a certain very few folders.

Here is the imap output:

* OK [CAPABILITY IMAP4REV1 LOGIN-REFERRALS STARTTLS AUTH=LOGIN]
fs3.imapserver.or
g IMAP4rev1 2003.338rh at Mon, 10 Apr 2006 12:50:43 +0100 (BST)

A006 THREAD REFERENCES ISO-8859-1 ALL

Connection to host lost.



It just dies after that command.
Is there any known cause for this behaviour? Could a particular message
itself cause the problem? I'm guessing so. I've tried moving all
messages to another folder and the problem still happens.

Many thanks for any tips!

It sounds like you encountered a bug.

Try running imapd under gdb (under a shell logged in as the user), and
repeat the THREAD command. You'll probably see where it crashed.

Even better, try upgrading from the old version that you are running,
which was an unreleased development snapshot, to the current release
version (which is imap-2004g). If the problem vanishes, blame it on the
old version and forget about it.

The current release version is:
ftp://ftp.cac.washington.edu/mail/imap.tar.Z
