java.lang.OutOfMemoryError: GC overhead limit exceeded

SA-56922

Summary



Server performance degrades and crashes with OutOfMemory error.


Error Messages



java.lang.OutOfMemoryError: GC overhead limit exceeded


Steps to Reproduce



Unknown


Root Cause



After analyzing the Garbage Collection (GC) logs, 87.85% of GC time was caused by 'Metadata GC Threshold'. The threshold was set to 2 GB, which was not sufficient.


Resolution



Perform the following local-change:

Tune the metaspace using below the below JVM argument.


-XX:MetaspaceSize=4 GB

This sets the size of the allocated class metadata space which triggers the GC the first time it is exceeded.
