Situation Description

Critical threshold exceeded for Average Occupancy Percent after Garbage Collection

 

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

 

Suggested Actions

Occupancy is the proportion of total Java heap that is in use after garbage collection. The JVM runtime tries to maintain a maximum occupancy between 40% and 70% of the total available heap. If occupancy goes above 70%, then the heap is expanded. If the heap is already at the maximum size, then there is a danger of storage shortage and OutOfMemory errors. This may indicate a possible memory leak in the application. If not, consider increasing the maximum heap size with Java option -mxnnnn; using a 64-bit JVM, or deploying some of the workload to another JVM.
