The temporary workaround would be to force the agents to reconnect. You have 3 options on how you could do this.

1. Restart data collection (from agent status page) highlight all the agents, stop/start data collection
2. If data collection doesn't resolve it, you could try to restart the nexus itself to force the agents to reconnect.
Nexus restart from jmx-console. This should disconnect all agents and upon restart connect it back again.
a. Login to jmx-console using the foglight user (http://fmshost:fmsport/jmx-console)
b. search for "com.quest.pas" and click on "service=JavaEE-Cartridge"
c. Invoke the 3 methods in that order…stop(), destroy(), start()
3. Restart the agents (appserver) Defect has been filed, JEE-7207. This will require a change to CDT itself which will not be patched.

STATUS: Issue has fixed in JavaEE Cartridge 5.8.0
