SYMPTOMS
TN3270 clients are unable to connect to the TN3270 Server until the TN3270 Server is restarted. When TN3270 clients are unable to connect, a network monitor trace shows that the server sends TCP/IP resets to TN3270 client connection requests.

There was a critical section deadlock in the TN3270 Server licensing code when a TN3270 client attempts to connect to the TN3270 Server at the same time that a TN3270 client disconnects.

STATUS
