Subject ConnectionLossException logs a lot on retry
Date Tue, 14 Jan 2014 15:19:55 GMT
Hi,
I've hit an issue where I get an error message way too often. This
message repeats about 10 times every millisecond, which fills our
disks with logs.
This happened when zookeeper went down.

Is this an issue with zookeeper or curator?
How can I configure this so that it's not logging extreme amounts?
