This appears to be a timing problem in the WLM code.Local fix Problem summary **************************************************************** * USERS AFFECTED: All WebSphere Application Server users * * of Version 4.0 / 4.0.1 that use WLM. * **************************************************************** * PROBLEM DESCRIPTION: Client side WLM problem where a * * java.io.UTFDataFormatException * * is reported. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a WLM client sends each request, a "version" (epoch) value is sent along with the request to represent how current the Server Group information is.Problem conclusion The epoch value is put into a hashtable with the thread name as the key. It was realized that this wasn't a unique enough key value. So the fix was to use the thread object reference as the key which worked.Temporary fix Comments
