> I am running a 5 node ZooKeeper cluster and I noticed that one of them has
> very high CPU usage:
> PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
> 6883 infact 22 0 725m 41m 4188 S 95 0.5
> 5671:54 java
> It is not "doing anything" application-wise at this point, so I was wondering
> why the heck it's using up so much CPU.
