Summary

0002848: JMX registration CPU issue

Description

(rep by Rajasekar Elango)

We are seeing an issue with JMX registration hogging when there is a restart of the server or a restart of the hub or any situation where the server and the hub lose communication and have to re-register all of the MBeans.

We looked at stack dump and it reveals that they are stuck some resin api's. Here is the stack trace:
