Subject Re: Need to create a stop-webapps.sh

I should clarify that using ZooKeeper pretty much requires that ManifoldCF
do things that cause these "error" messages to be dumped.  Each time a new
lock key is created this happens.  At a certain point, though, all the
possible locks are created and ZK is happy. ;-)
