Steps to Reproduce
Unknown
Root Cause
According to the Log file, a particular business process was triggered by various users, and brought back a large database payload. This JVM Heap Memory was not released after use, and consumed the heap space. Normal JVM Garbage Collection (GC) operations were observed, and memory was released. However, user interaction with this process, occurred with greater frequency than the GC operations. This lead to a gradual and complete exhaustion of the heap space.
Resolution
- Review the business process.
- Implement the PAGE-REMOVE activity method step calls as required in the code.
- Ensure that all report definitions, list views, and OBJ-LIST and OBJ-BROWSE operations incorporate the correct and minimal filter to retrieve only those data items which are required from the database.
