Error description
After issuing the PauseListeners command the Control Region logs may show HTTP request failed error messages. This is because the accepted HTTP requests were not processed before before the PAUSELISTENERS took affect. Control Region Job Log error message: SourceId:com.ibm.ws390.xmem.proxy.channel.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V8.5 and V9.0 * **************************************************************** * PROBLEM DESCRIPTION: WebSphere Application Server for z/OS * * produced a java.io.IOException * * processing a HTTP request while * * paused. * **************************************************************** * RECOMMENDATION: * **************************************************************** A "f <server>,pauselisteners" z/OS command was issued to the Server. Internal processing of the Server will immediately start to reject certain requests after the pause. Any received HTTP or HTTP SSL request that was received just prior to the pauselisteners command may be rejected and receive the following exception: java.io.IOException: Exception occured during native method call from JAVA at com.ibm.ws390.xmem.proxy.XMemProxyCRCppUtilities. queueInboundRequest(Native Method) at com.ibm.ws390.xmem.proxy.channel.

Problem conclusion
Code has been modified to allow an HTTP request that was inflight when the Server was paused to be processed as long as a Servant is available. The connection will be closed and subsequent connect requests will fail until the Server is resumed. APAR PI73950 is currently targeted for inclusion in Fix Packs 8.5.5.12 and 9.0.0.4 of WebSphere Application Server. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980 In addition, please refer to URL: http://www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack PTF information.
