Problem summary
**************************************************************** * USERS AFFECTED: Users of the WebSphere Application Server * * V7.0 Plugin with SSL and on all platforms.* **************************************************************** * PROBLEM DESCRIPTION: Responses may be delayed for a fixed * * period of 30 seconds or the current * * AppServer KeepAlive timeout * **************************************************************** * RECOMMENDATION: Apply this fix if a transport in * * plugin-cfg.xml uses both SSL and * * ServerIOTimeout. * **************************************************************** If a non-zero ServerIOTimeout is used with an SSL transport in plugin-cfg.xml, the WebSphere Plugin may block at the end of a response under the false impression that data isn't currently available. The Plugin is not unblocked until the Application Server closes the HTTP/1.1 keepalive connection, at which point the remaining data is acknowledged. Corresponding Application Server traces show that all data was flushed without delay. TCP packet captures show the Plugin didn't unblock until an SSL close_notify or TCP FIN was received.
Problem conclusion
The WebSphere Plugin was updated to exhaust all data potentially buffered by the security library before performing a poll() or select() on the underlying socket. APAR PK89706 is currently targeted for inclusion in Service Level (Fix Pack) 7.0.07 of WebSphere Application Server V7.0 of the WebSphere Plugin. Please refer to URL: //www.ibm.com/support/docview.wss?rs=404&uid=swg27006970 for Fix Pack availability.
