/var/imap filling up quickly

[Erin B. Peszko]

We're experiencing the problem of our /var/imap partition filling up (to
100% capacity) very quickly, typically during the day where there may be
around 3000 imapd processes running. We're suspecting that there needs to
be a 'close mailboxes' in some part of the code where there currently
isn't. 

Is anyone else experiencing this? Have a solution?

Solaris 2.5.1
Cyrus IMAP4 v1.5.14

Responses much appreciated,
