Issue/Introduction

Error Message :
ErrorMsg: AwE-9999 Internal error (2/12/16 10:39 PM)
Details: predTester load
java.lang.OutOfMemoryError: Java heap space

When running an Applications Manager (AM) Master on a Windows 32-bit machine, the OS can only allocate 1.5 GB of JVM memory.  

If that limit is reached, AM can become unresponsive and the above error message is displayed.

This usually occurs when a large load is being processed through the Master with many Client connections and very large Workflows are being executed, which cause the OutOfMemoryError message.
 

Cause

Configuration
