Environment

Release : 11.5, 12.x

OS: Linux, UNIX

Component: Workload Automation System Agent

Cause

The WA Agent uses InstallAnyhwere Uninstaller to uninstall on Linux/Unix and Windows.  The error "java.lang.OutOfMemoryError: Java heap space" is likely due to inadequate memory.  Uninstaller JVM will use its own memory space, not to be confused by memory set in the agentparm.txt.  By default it will use up to 500 MB.

Resolution

Make sure the OS has about 500 MB of free memory.  If the problem persists, stop the agent and delete the agent directory manually (only on Linux and UNIX).  

Remove any startup scripts in /etc/init.d manually and disable the service if Linux is using sytemctl

systemctl disable <service_name>

For Windows, please refer to this KD.
