APAR status
Closed as program error.
Error description
In specific situations, the Double Click handler will be tracking the set of requests that are detected to be repetitive (double click) requests from the same user for the same parameters. To help prevent unnecessary processing and concurrency issues that can arise due to these situations the Double Click Handler feature of WebSphere Commerce will keep track of these situations and handle them accordingly. In the process, it is possible for the code which manages these requests to keep information in memory which is no longer needed, resulting in a memory leak. If enough objects are leaked, performance degradation maybe noted due to a reduction in free memory, which may lead to an Out of Memory condition in extreme cases.
Local fix
In the event of memory loss, the server can be restarted to reset the memory usage.
Problem summary
USERS AFFECTED: Users who have enabled the Double Click handling functionality of WebSphere Commerce and who frequently have situations where users leverage this functionality. PROBLEM ABSTRACT: Memory leak can occur in in the Double Click Handler functions of WebSphere Commerce BUSINESS IMPACT: In extreme cases, it is possible that if enough memory is leaked, the system can run into Out of Memory errors and have reduced performance. RECOMMENDATION:
Problem conclusion
The Double Click management code now correctly clears unnecessary references upon the completion of handling requests which triggered the need for double click handling. ------------------------------------------------------------- The latest available maintenance information can be obtained from the Recommended Fixes for WebSphere Commerce technote: http://www.ibm.com/support/docview.wss?rs=3046&uid=swg21261296
