[Dovecot] hanging imap... and users getting other users' emails!

Hi All,

    We recently upgraded from UW (boy, starting to sound like a broken 
record, eh?)...

    Two problems:

    1. Every two or three days users are unable to access their email 
via IMAP. It seems that it's because dovecot-auth has hung. Has anyone 
seen anything like this? 

    2. (the really serious one)... one of our users, "angie" has twice 
had her Outlook download other users' email! Once as another user, 
"helene", and just now as "mkarlin". The first time she got 800 of 
helene's email, and just now, about 30 of mkarlin's.... from our log, I 
noticed:


Mar  2 17:27:10 core imap-login: Login: mkarlin [::ffff:128.195.131.2]
Mar  2 17:27:10 core imap-login: Login: mkarlin [::ffff:128.195.131.2]
Mar  2 17:27:11 core pop3-login: Login: angie [::ffff:68.231.223.128]
Mar  2 17:27:11 core imap-login: Login: mkarlin [::ffff:128.195.131.2]
Mar  2 17:27:11 core imap-login: Login: mkarlin [::ffff:128.195.131.2]


Our server setup:

Fedora Core 3. dovecot-0.99.13. OpenLDAP, and dovecot auth'ing off PAM 
(mostly default setup, using Mailbox, and mail/ as a subdir).

Any ideas? Any more debug info I can supply?
