[Java SE] GC Is Extremely Slow Due to System CPU Being Overloaded (Doc ID 1570441.1)

Last updated on APRIL 15, 2024

Applies to:

Java SE JDK and JRE - Version 1.3.1 and later
Information in this document applies to any platform.

Symptoms

Garbage Collection (GC) takes a very long time to complete.  During this time all application threads are paused and the application seems to hang.  If the Java option -XX:+PrintGCDetails is used to report the GC activity, the "real" time will be reported as being far greater than the "user" and "sys" times combined.
