Error description
If an On-Demand Router (ODR) or WebSphere Application Server Proxy is configured with a trusted intermediary, a header is sent in requests to the server which will result in excessive creation of VersionValues objects. You might see something like the following from a heapdump after processing with HeapAnalyzer.

Local fix
N/A However if you encounter problems with your file system filling up with heapdumps, please check the IBM WebSphere Application Server Infocenter for information on setting the JAVA_DUMP_OPTS environment variable. This will limit the number of dumps created.
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V6.0.2 and V6.1 Proxy Server and * * On-Demand Router (ODR) * **************************************************************** * PROBLEM DESCRIPTION: Memory leaking when trusted * * intermediary is configured * **************************************************************** * RECOMMENDATION: * **************************************************************** If an ODR or Proxy Server is configured with a trusted intermediary, a header is sent in requests to the server which will result in excessive creation of VersionValues objects.
