Out of Memory errors occur when using L3 and hotspot JVM
The problem: If out of memory errors occur while you are using L3 and hotspot JVM, do the following instructions.
The cause: The default NewSize and MaxNewSize might be too small for some Applications if the Application is allocating large numbers of short living objects.
The solution: Some recommended tuning for an application that allocates many short living objects is as the following content:
-XX:+DisableExplicitGC -XX:NewSize=128m -XX:MaxNewSize=256m -XconcurrentioNewSize and MaxNewSize must be changed based on the Maximum and Minimum heap settings of the JVM.
