Subject Re: 200k fate locks in zookeeper [SEC=UNOFFICIAL]
Date Tue, 27 May 2014 15:48:06 GMT
The zookeeper admin manual say that prop is a java system property.  So one
way to set it is via the java command line.   Could modify
and modify the servers java options to add -Djute.maxbuffer=XX  I am not
sure what formats that property accepts.
