I seem to remember a similar red alert last year for all the then = supported zOS releases. I'm surprised this popped up again under zOS = 1.11.

Description: A logic error in TCPIP on z/OS 1.11 can cause applications using ASYNCIO = Writes to be driven twice. The application data presented on the socket = write operation is sent over the TCP connection twice, thus corrupting = the data stream.
