The priv1.stm file is growing after 1 solid year of remaining exactly the same size. It has grown approx 150 meg in 3 days.

Exchange Server 2003 Service pack 1. The size of priv1.edb has been virtually the same for the entire past year with an average of 3.5 gigs of free white space within the information store database. Mailbox manager has been managing the overall size of the information store wonderfully.
Research tells me that a typical .stm is audio, video, and any streaming MIME data. Is this correct? If so why after more than a year would it start to grow now. I find it hard to believe that one or more users have not attached such a file to email in the past.
I run nightly full evault backups and the transaction log files are getting truncated.
Can someone please advise a course of action. I prefer not to run eseutil at this time as Mailbox Manager, with its current settings, is managing the overall size of the database very well.
I should add that the only recent change to our environment was the addition of paperless fax. Castelle Faxpress Appliance. The appliance does act as an smtp client to transport faxes. There is no connector installed on the exchange server and attachments are either pdf or tif so at this point in time I cannot see how that new system could be affecting the growth of the stm file.
