SYMPTOMS

You may see an application exception with SNA Server after an update to 3270 (or LUA) LUs on an active server. This application exception occurs when one or more of the updates cannot be immediately enacted (the SNA Server will appear "out-of-date" in the SNA Server Administrator program) and you then attempt to activate/deactivate a connection on the computer running SNA Server.

When this problem occurs, SNA Server generates a Dr. Watson error. The Drwtsn32.log file indicates that an application exception has occurred in Snaservr.exe, in the sapugeti function. In addition, SNA Server may log an Event 624 in the Windows NT Application Event log when the Snaservr.exe application exception occurs.

RESOLUTION

A fix is available to correct this problem.

STATUS

Microsoft has confirmed this to be a problem in SNA Server versions 2.0, 2.1, 2.11, and 2.11 SP1.
This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION

Event 624 in the Windows NT Application Event log has a description similar to the following:
Creating dump file C:\SNA\traces\snadump.log for SNASERVR.EXE

EXPLANATION
A process (SNASERVR.EXE) ended abnormally due to a protection violation or similar condition and a dump file SNADUMP.LOG has been created that contains information about the state of the process at the time of the exception. Register information is contained in your Windows NT root directory in the file DRWTSN32.LOG.
The Drwtsn32.log will contain information similar to the following excerpt: 
   Application exception occurred:
        App: snaservr.exe (pid=221)
        When: 12/12/1996 @ 14:23:51.8
