XCON: Memory Leak in Microsoft Exchange Message Transfer Agent (176708)
The information in this article applies to:
- Microsoft Exchange Server 5.0
This article was previously published under Q176708 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. For information on obtaining the
Service Pack, query on the following word in the Microsoft Knowledge Base
