![]() APAR status Closed as program error. Error description Abstract:Application server locks up with threads in socketWrite Desc: A defect in the plugin to application server connection cleanup code could cause connections to be orphaned when ESI is enabled. Each orphaned connection can potentially tie up the appserver thread, until all of the threads are exhausted.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server 5.0 plugin * * users with ESI enabled. * **************************************************************** * PROBLEM DESCRIPTION: TCP connections orphaned between the * * application server and plugins. * **************************************************************** * RECOMMENDATION: * **************************************************************** A defect was introduced with the introduction of ESI to the plugin source code that made it so connection cleanup code was not called for some requests that experienced early connection closes. This would cause a build up of orphaned connections between the application server and the plugins that could eventually result in the application server hanging up with all of it's worker threads hanging in socketWrite calls.Problem conclusion The cleanup code was repaired for the ESI case, so the connections will no longer be orphaned in exceptional cases.Temporary fix Comments
