Subject: Re: Locator high cpu
What is the memory usage of the locator? Do you have any JMX clients or Pulse
running? Can you get a few thread dumps of the locator JVM? That should help
determine what the threads are doing.

We have a gemfire client/server cluster that we’ve noticed our locator is
running a sustained 50 – 100% cpu utilization. We stopped all work in this
environment (test) and the cpu has remained the same. We are running gemfire
v8.1, java 1.7 on linux VM RHEL 6. Any suggestions on what to look at to see
what may be causing this?
Thanks.
