Communications Server for Windows --------------------------------- TN3270 clients lose connection to the server. On the server, Dr. Watson logs a trap: Application exception occurred: App: TN3270WN.EXE (pid=4868) Exception number: c0000005 (access violation)
Restart the server.
The trap data shows two problems: 1) If a client sends in multiple connection requests too quickly, a memory initialization bug can be hit, because a certain control block was not being initialized properly. This could lead to an attempt to re-use an expired semaphore, causing the trap. 2) This was exposed by fixing problem (1). If a client requestes an LU that is not defined on the host, the server may return the error response without waiting for internal processing to complete. If the request is repeated too quickly, it could overwrite the first request and cause the server to hang.
Code has been corrected to properly initialize the control block at each new client connection. Code has also been corrected to prevent conflict with multiple requests for a non-existant LU.
