SYMPTOM(s):

HPUX 11 running 9.1D Java 1.3.0 process consumes large amounts of CPU (as much as 300% CPU)

Java version 1.3.0

FACT(s) (Environment):

HP-UX 11.x
Progress 9.1D
Progress 9.1C

CAUSE:

The method that the JAVA 1.3.0 performs garbage collection can cause large delays while the garbage collection is occurring.

This was creating an error condition within Progress since the length of time for the Java Garbage collection exceeded an internal limit for response.

Part of why the Garbage Collection takes so long in the 1.3.0 version is due to use of an HP spin lock algorithm within the Java. That algorithm has since been replaced with a better methodology in newer HP Java versions.

FIX:

Upgrade the version of Java to 1.3.1.
