I think the problem is caused because some user is choosing the 
option of leaving the mail on the server and their mailbox has become 
very large.  This causes problem at close down when:

         1.  The mailbox is copied to the temporary .pop file.

         2.  The .pop file is copied back to the user mailbox
             while eliminating any deleted messages.

All the file copying IO can be crippling specially if the temporary 
files are not on a different disk spindle as the mailboxes.

Take a look at the size of you user's mailboxes when this problem is occurring.
