Troubleshooting
Problem
How to disable frequent Garbage Collection (GC) calls from the application/agent.
Symptom
Frequent Garbage Collection impacting system performance may require disabling System.gc() calls from the application/agent.
Error MessageWhen frequent System Garbage Collection calls are issued by an application (without having Full GCs), the result is significant time spent on overall Garbage Collection.
Resolving The Problem
There are times that the application or the custom code or even specific AppServer/JVM settings can cause frequent System.gc () calls instead of forcing Full GC. This could deteriorate the overall system performance as significant time is spent on System.gc (). This is true when the Full GC does not take place periodically.
A quick workaround is to disable the System.gc () and force a Full GC.
The –XX:+DisableExplicitGC command can be passed as a java parameter that disables System.gc() for the JVM.
This virtually enables Full GCs when necessary.
