************************************************

Version-Release number of selected component (if applicable):
JBoss ON 3.3.3 

How reproducible:
Unfortunately no repo steps. 


According to the solution: "rhq.ear/rhq-core-domain-ejb3.jar#rhqpu" resource unavailable in JBoss ON (https://access.redhat.com/solutions/735903) - this error will happen when rhq.ear/rhq-core-domain-ejb3.jar#rhqpu resource (bean) is not active for a longer time period. In that case, this bean will be passivated and as such it's availability will be considered as DOWN although it is really UP. The issue was logged previously against JBoss ON 3.2.0 ER5 in Bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1028468 and was closed as fixed in JBoss ON 3.3.0.
