dovecot - May 2005 - fcntl lock timout on maildir format Trash .index file under OpenBSD sparc64

Whenever I attempt to retrieve or delete mail (Using thunderbird win 
client) operation takes several minutes. right before completion posts 
the following error to maillog:

May 14 10:22:04 NAPUtil imap(djrobert): Timeout while waiting for 
release of shared fcntl() lock for index file 
/home/djrobert/Maildir/.Trash/.imap.index

deleting the index file speeds up the operation once. subsequent 
operations are slow again

I don't know what other process is placing a lock on the file. or how to 
clear it.
I am running the 9914p0 package distributed with a march 11 3.7 snapshot 
(OS loaded from the same snapshot). I previously was running the release 
3.6 OS and the Dovecot package that came with the CD. both installs 
exhibit the same behavior.

Both Dovecot and postfix are configured with fcntl locking only.

What the heck am I doing wrong?

Thanks,
Dale

Probably happens because Thunderbird creates multiple connections to the
mailbox. That itself shouldn't break it though, but maybe there are some
openbsd-specific problems.

You could probably configure Thunderbird to use only one connection and
it should fix it. Alternatively you could upgrade to latest 1.0-stable
or 1.0-test release where this should never happen.
