If the first request isn't complete in 15 seconds then the next request is started and so on. Each request counts the tasks and requires the memory for this. Through the parallel threads the memory consumption increases til a OOM occurs.

Problem summary
CPU starvation and OOM might occur when viewing role bindings tab PROBLEM DETAILED DESCRIPTION: If the customer clicks Role Binding in the Process Admin Console then every 15 seconds a refresh triggers a new request to get the Role Binding information. If the first request isn't complete in 15 seconds then the next request is started and so on. Each request counts the tasks and requires the memory for this. Due to the parallel threads the memory consumption increases until a OOM occurs.
Problem conclusion
We inserted a configuration property to define the refresh rate. Please add the following lines to your 100Custom.xml in the server section <server> <!-- create if not already present> <process-admin-console> <refresh-interval>Refresh time in milliseconds </refresh-interval> </process-admin-console> </server> <!-- create if not already present> FIX AVAILABILITY: iFix for 7.5.1.1 is/will be available on Fix Central; search for APAR JR48822 at http://www.ibm.com/support/fixcentral/ Fix is also targetted for inclusion in next fixpack for BPM V7.5.1, BPM 8.0.1 When obtaining any of the above fixes, be sure to download the accompanying readme, for itself, and any prerequisite fixes, and review them thorougly.
