SYMPTOMS
========

When you print from a TN3270 emulator session, an internal memory leak may occur
in the TN3270 Server service, causing the server to eventually run out of
virtual memory.

If you view the Tn3servr.exe file in Task Manager or Performance Monitor, you
will see that the memory use rises at a fairly high rate (10 to 20 megabytes in
a 12-hour period).


RESOLUTION
==========

To resolve this problem, obtain the latest service pack for SNA Server 4.0. For
additional information, please see the following article in the Microsoft
Knowledge Base:

STATUS
======

4.0.

This problem was first corrected in SNA Server 4.0 Service Pack 4.
