Subject Re: ouch, zookeeper infinite loop

Thanks for the report, entered as:
https://issues.apache.org/jira/browse/ZOOKEEPER-268

For the time being you can work around this by setting the threshold to 
INFO for that class (in log4j.properties). Either that or just set the 
data to a non-empty value for the znode.
