Running dovecot on Solaris 8 sparc with SylpheedClaws as the MUA.

I tried moving to many messages from a folder to my maildir folder, which is a local directory on the dovecot server.

Now, I cannot open the folder due to this message: 'Mar 20 10:26:15 sws601.mcsun.local imap(amoore): [ID 702911 mail.error] Timeout while waiting for release of shared fcntl() lock for index file /var/indexes//amoore/.Spam.Spam Archive/.imap.index'

How do I get the lock released? I changed some timeout settings in dovecot.conf, but that did not help. Every time that I click this particular folder in my MUA, the screen locks up.

Thanks, Alex
