EDB and STM files grow continually - Part 3

I have been involved in a couple of cases where the Exchange EDB and STM files have continually grown much faster than expected, even when users are regularly deleting their old mail and emptying their Deleted Items folders.

Deleted items and deleted mailboxes are purged nightly during online maintenance. The online mainteance interval is set (by default) daily between 1:00AM and 5:00AM. This is set on the Database property page for EACH mailbox store.

Note: Online backups WILL halt online maintenance on all stores in the storage group, so schedule online backups to occur so that it does not conflict with online maintenance.

Online maintenance should run at least once per day on all stores in a server. How can you tell if online maintenace is running? The following informational events should be logged in the event viewer's application log for each mailbox store. These are from one of my test servers called KILAUEA.
