The streaming db file (priv1.stm) for my exchange 2000 server has started growing somewhere around 1GB per hour. After an offline defrag, it is 4.75GB, and then grows to 10GB, at which point the information store dismounts, and I have to do an offline defrag again.
After a few quick searches all I've turned up is references to improperly configured anti-virus software or spam/relaying. There is no anti-virus software on this server. The incoming mail all goes through a spam filtering service.
The only thing that has recently changed is I took one user's mailbox out w/ exmerge, then killed and purged his mailbox, then recreated. It seems as though when I notice the size of the stm file growing (its not constant, its on and off) he is one of the most recent logons to the store. Neither he nor the server have the bandwidth to support that much data, but maybe the stm file is growing at a different rate than it's receiving info?
Anyway, I'll try disabling his account for the rest of the day and see if that helps. Any help is appreciated.
