BIG PROBLEM: Need help with production box

[Curtis Robinson]

Sorry, I forgot to mention that.

All mailboxes have quotas of 100MB.
Now, the users that are logged into the run away process generally have a couple of megs to around 70 MBs.
The process do not stop at the size of the users mailbox.

Mailboxes: skiplist
The rest are default build options.
Here is the build options I picked:
./configure             \
--with-mboxlist-db=skiplist \
--with-openssl          \
--enable-listext        \
--enable-annotatemore   \
--with-krb=/usr/kerberos \
--with-sasl             \
--with-perl             \
--with-libwrap          \
--with-ucdsnmp          \
--with-auth=unix

I'm cynical, but I'd say it's a Redhat problem LOL...more seriously though 
what is the size of your dbs mailboxes file, what DB type?  Any 
particularly 'bushy' mailboxes?
