Defect #1765
Updated by Alena Peterová almost 5 years ago
Version 9.6.3, 9.7.0-SNAPSHOT
When the DeleteExecutedEventTaskExecutor starts, it runs some minutes and then causes OutOfMemory on java heap. The application doesn't respond. The only solution is to restart Tomcat.
There are:
352739 Events
339623 Executed events
303578 Executed events older than 3 days
You can see attached log from Tomcat.
* First there is OutOfMemory after night task (the start of the task was at 2:00 and it is not in the logfile, because log is rotated).
* Then I restarted Tomcat and run DeleteExecutedEventTaskExecutor directly after restart of IdM.

Java heap (6 GB) was soon filled, only full garbage collector run with no success:
