SYMPTOMS
The SNA Server 2.11 Service Pack 1 Tn3270E Server may experience access violations when more than two thousand clients are connected to the TN3270 Server.

If this occurs, the SNA Server TN3270E service will log the following event into the Microsoft Windows NT application event log:

Event Id:5

The TN3270E Service has abnormally terminated.

EXPLANATION

An exception (0xC0000005) has occurred that has caused the TN3270E

Service to terminate.

ACTION

Record message and contact technical support.



CAUSE
The TN3270E Server will start to write beyond the bounds of one of its arrays when more than 2000 users are connected to the server.



STATUS
Microsoft has confirmed this to be a problem in Microsoft SNA Server for Windows NT versions 2.11 and 2.11.sp1. A fix to this problem is in development, but has not been regression-tested and may be destabilizing in production environments. Microsoft does not recommend implementing this fix at this time.
