      1. 'Fuse 6.3.0 + Int Pack fuse-integration-eap-full-1.7.0.redhat-630013-installer.zip'

      2. Deploy the 'switchyard-rules-interview' quickstart

      3. Execute the quickstart in a loop:

      #!/bin/bash
for i in {1..5000}
do
   echo "Sending request $i"
   cp src/test/resources/xml/soap-request-pass.xml request.xml
   sed -i "s/_AGE_/${i}/g" request.xml
   curl --header "Content-Type: text/xml;charset=UTF-8" --header "SOAPAction:verify" --data @request.xml http://localhost:8080/rules-interview/Interview
   echo ""
   sleep 0.05
done

      Running a Switchyard application that uses rules component, similar to the `switchyard-rules-interview` quickstart, a memory leak can be observed:

      1. One StatefulKnowledgeSessionImpl instance for each service invocation in the org.jbpm.runtime.manager.impl.factory.InMemorySessionFactory.sessions hashmap

      2. A Large number of org.jbpm.runtime.manager.impl.RuntimeEngineImpl instances referenced by a ThreadLocal

      See the text file with the relevant heap dump extracts attached.
