Situation Description

Warning issued for System (forced) Garbage Collections in application code.

 

Possible Causes
  1. An application in the JVM is issuing System.gc() method calls in an attempt to influence Garbage Collection.

 

Suggested Actions

The JVM runtime usually does an excellent job in managing the Java heap. Some application programmers use the System.gc() method call to release memory. This is normally unnecessary and often adversely affects the JVM by executing global garbage collections which can cause the JVM to pause.
