The client seeing the problem in this case is 3.3.0, I see this based on the line number in the stack trace not matching up with 3.3.3, with 3.3.0 it's this line: event.setPath(serverPath.substring(chrootPath.length())); so for some reason your chroot path is negative in length?

Ted, Yes, we could have used just 3 servers. It just happens that we are overlapping ZK servers on each of the 4 Kafka servers. Jun On Tue, Aug 23, 2011 at 4:07 PM, Ted Dunning ted.dunn...@gmail.com wrote: Jun, I don't see what your connection loss problem is, but I do have a question

This looks very strange to me. Is it possible that there is version issue with ZK server and client? Mostly looks like the client is getting garbled data from the server somehow. I cant imagine how that would happen. Is it possible to run one of the servers on tracemode and see the tracelog on
