done

cat >>"${tmpDir}"/deploy.xml <<EOF
    </rhq:deployment-unit>
  </rhq:bundle>
</project>
EOF
(cd "${tmpDir}" && zip -r /tmp/large-bundle.zip .)
rm -rf "${tmpDir}"
ls -al /tmp/large-bundle.zip

3.  Create a bundle group:

    *   *Name:* `Test01 - Bundle Group`

4. Create new bundle using _/tmp/large-bundle.zip_ and assign it to the _Test01 - Bundle Group_ bundle group.

5. After bundle is created, select the bundle from Bundles menu in UI and click Deploy.
6. Enter Destination name, Select Resource Group as 'DynaGroup - Groups By Platform (Linux).
7. Enter Destination Directory (Ex: /tmp/Test) and click Next.
8. Select Deployment version and click Next->Next->Next and Finish.
9. Observe the agent log for errors.

Actual results:

Large bundle deployment results in OOM error in agent log if deploy.xml has attribute replace="true"

Expected results:

No errors

Additional info:

1) The bundle gets deployed successfully without error if I set : RHQ_AGENT_JAVA_OPTS="-Xms1024m -Xmx1024m -XX:PermSize=256M -XX:MaxPermSize=256M -Djava.net.preferIPv4Stack=true" in 'agentRoot/rhq-agent/bin/rhq-agent-env.sh'

2) If the attribute 'replace in deploy.xml is changed to false (replace="false"). The deployment is successful without errors.
