Situation Description
Suggested Actions
Situation Description

Critical threshold exceeded for Average Occupancy Percent after Global Garbage Collection.

 

Possible Causes
  1. There is insufficient free Java heap available after the last global garbage collection. 

 

Suggested Actions

Heap Occupancy After Global GC is the proportion of total Java heap that is in use after the last global garbage collection.  Global GCs recover memory in both the nursery and tenure regions of the heap.  A high proportion of heap occupied by live objects could lead to a storage shortage and the possibility of OutOfMemory errors. This may indicate a possible memory leak in the application. If not, consider increasing the maximum heap size with Java option -Xmx; using a 64-bit JVM, or deploying some of the workload to another JVM.
