Error description
There is a timing window that can cause an abendDC3 RC 03080002 after a Modify RESUMELISTENERS is done. The issue is when a new connection is being accepted and a new accept is issued on the listener socket right around the same time as the Modify PAUSELISTENERS, the new accept can fail. In response to an accept failure, a repeating 15 second timer to reconnect is started (with the idea that there is a TCP/IP problem and we need to retry the accept at a later time when TCP/IP recovers). In this case, however, TCP/IP is fine since the listener socket was being closed by the Modify PAUSELISTENERS. 15 seconds later the timer fires, and since there is not a TCP/IP problem, it reactivates the listener. When the Modify RESUMELISTENERS is done later on, the abendDC3 RC 03080002 occurs because the listener is already active with an accept on it.

Problem conclusion
Updated the stop code to not create a timer when a modify pauselisteners has been issued. The fix for this APAR is currently targeted for inclusion in fix pack 8.0.0.14, 8.5.5.13 and 9.0.0.6.
