> Drools JBRMS has a memory leak when the RulesAgent accesses the BRMS to check the status of a snapshot.
> If a RuleAgent is configured with
> url=http://localhost:8080/.../package/NAME/SNAPSHOT
> poll=60
> then the memory usage in the VM will increase until eventually it runs out of memory.
> This can be observed using jconsole.
> The problem lies in 
> drools-jbrms
> org.drools.brms.server.files.FileManagerUtils.java
> This creates a Seam EVENT each time the RuleAgent accesses the GUI,
> the EVENT is only in context for the event, so it creates a RulesRepository during creation,
> but it never releases the RulesRepository so a session is left open, and the Event cannot be GC.
> Fix is

> < import org.jboss.seam.annotations.Destroy;
> 64,67d62
> <     @Destroy
> <     public void close(){
> <         repository.logout();
> <     }
