Thanks for your post and others' suggestions.
In addition to checking SBS BPA report and system disk space, did you notice that the Microsoft Exchange System Attendant is set to Automatic and started? Does the issue still
occurs if you manually restart the Exchange System Attendant service?
BTW, please check and make sure the latest Exchange server 2007 SP2 is applied. Also, please temporarily disable all 3rd party anti-virus/anti-spam software as incorrect
configuration of these software may cause Exchange engine to crash.

Hope this helps.
