Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server web server Plugin users * **************************************************************** * PROBLEM DESCRIPTION: The web server indicates a crash * * occurred. Crash details indicate the * * crash occurred Plugin's detailedLog * * function. * **************************************************************** * RECOMMENDATION: * **************************************************************** The web server crashes in Plugin's detailedLog function due to an invalid memory location of the 3rd parameter passed to the function. Call stack indicates detailedLog was invoked by webSphereExecute. The issue can occur after the plugin fails to receive a response to a request forwarded to the WebSphere Application server.
Problem conclusion
The plugin module closes the socket to the WebSphere Application Server after a request failure. Plugin attempted to log error information including some socket details after the socket was closed. If the memory is reused before the data is logged, a memory access violation can occur. The fix for this APAR is targeted for inclusion in fix pack 8.5.5.24 and 9.0.5.17.
