SYMPTOMS
When a Microsoft Exchange Server is left running for a long period of time, it might run out of virtual memory due to a memory leak in the Microsoft Exchange message transfer agent (MTA). This can be observed using the Windows NT Performance Monitor, by checking the private byte counter of the Store process. If you see a steady increase over a few days, you are seeing this problem. Even though you are seeing a leak from Store, it is actually in the MTA.
CAUSE
The MTA is not freeing allocated memory properly. The store is showing the problem because it is calling a function exported from the MTA.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server, version 5.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0.
