Lars George commented on ZOOKEEPER-883:

Here is the config, which is a modified CDH3 version, pretty much standard:

# The number of milliseconds of each tick
# The number of ticks that the initial
# synchronization phase can take
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
# the directory where the snapshot is stored.
# the port at which the clients will connect

> Idle cluster increasingly consumes CPU resources

> Monitoring the ZooKeeper nodes by polling the various ports using Nagios' 
> open port checks seems to cause a substantial raise of CPU being used by the 
> ZooKeeper daemons. Over the course of a week an idle cluster grew from a 
> baseline 2% to >10% CPU usage. Attached is a stack dump and logs showing the 
> occupied threads. At the end the daemon starts failing on "too many open 
> files" errors as all handles are used up.
