SYMPTOMS

The TN3270 service may unexpectedly stop responding, causing all attached TN3270 client users to lose their sessions. When this occurs, an <ntroot>\drwtsn32.log file may be created, indicating a "FAULT" in the following routine: 
   FramePtr  RetAddr   Param1   Param2   Param3   Function Name
   0c74fc94  0011c0e2  0bf62c18 0bf64382 0bf643d4
   TN3SERVR!SRSGetSpecificResource+0x28e
The TN3270 service must be restarted to recover.

CAUSE

This TN3270 failure can occur if an LUA Pool (with an active session) is deleted from the configuration file. Further attempts to access the pool will lead to a TN3270 access violation.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 2.11 (including SP1 and SP2) and 3.0 (including SP1 and SP2).

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):
