XADM: Paged Pool Memory Leak Caused by Attachment Processing |
The information in this article applies to:
-
Microsoft Exchange Server, versions 5.0, 5.5
SYMPTOMS
While using a MAPI application that processes attachments, paged pool
memory increases over time without decreasing. There may be visible
problems with the desktop user-interface failing to process normally
(failing to repaint the screen properly, and missing images).
CAUSE
When MAPI tries to obtain an icon image to display for the file attachment,
memory is allocated for the icon, and is not freed. The memory allocation
is small, but some messaging applications which process many messages with
attachments may be subject to this problem.
RESOLUTION
MAPI has been corrected to free the memory allocation.
Exchange Server 5.0
A supported fix that corrects this problem is now available from Microsoft,
but has not been fully regression-tested and should be applied only to

affected by this specific problem, Microsoft recommends that you wait for
the next Microsoft Exchange Server version 5.0 service pack that contains
this fix.
