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:
