    Description

      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.
