This is generally indicative of a client going through large number > of GC and hence disconnecting way too often from a zookeeper cluster. > Today, this information is only indirectly exposed as part of the stat > command which requires counting the results. That's alot of work for the > server to do just to get connection count. > For monitoring purposes, it will be useful to have this exposed through JMX > and 4lw srvr. -- This message is automatically generated by JIRA.
