SNA Print Service Leak When All Print Sessions Are Stopped

The information in this article applies to:

• Microsoft SNA Server versions 3.0 and 3.0 SP1

SYMPTOMS

Memory is not de-allocated when all print sessions are stopped.

CAUSE

SNA Print service fails to de-allocate 317 KB of memory after each time all printer session are stopped.

Every time a first session starts, a new thread is created. When the number of sessions goes down to zero, the thread is destroyed but not all memory hanging off this thread is freed.

STATUS

Microsoft has confirmed this to be a problem in SNA Server 3.0 and 3.0 sp1. This problem was corrected in the latest SNA Server version 3.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION

A change was made so that threads are never destroyed until SNAPrint Service is actually stopped. The threads will wait around until a new session uses them.
