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.
