Hi Zookeeper users I think that we are having an issue similar to https://issues.apache.org/jira/browse/ZOOKEEPER-706
I can see the following log lines repeated and I am suspecting some application is trying to acquire a number of InterProcessMutex, one of Apache Curator recipe. 2013-11-08 20:53:10,782 - WARN [NIOServerCxn.Factory: 0.0.0.0/0.0.0.0:2181:NIOServerCnxn@354] - Exception causing close of session 0xb1422ec35d9402e6 due to java.io.IOException: Len error 271603750 2013-11-08 20:53:10,783 - INFO [NIOServerCxn.Factory: 0.0.0.0/0.0.0.0:2181:NIOServerCnxn@1001] - Closed socket connection for client /10.45.164.229:51904 which had sessionid 0xb1422ec35d9402e6 2013-11-08 20:53:10,853 - WARN [NIOServerCxn.Factory: 0.0.0.0/0.0.0.0:2181:NIOServerCnxn@354] - Exception causing close of session 0xb3422ec35f3c0228 due to java.io.IOException: Len error 28936498 2013-11-08 20:53:10,854 - INFO [NIOServerCxn.Factory: 0.0.0.0/0.0.0.0:2181:NIOServerCnxn@1001] - Closed socket connection for client /10.154.133.50:51193 which had sessionid 0xb3422ec35f3c0228 So, the solution can be increasing jute.maxbuffer and according to the zookeeper administrator's guide, it should be set in both server and the client. What will happen when some clients are not setting that property? I cannot urge all clients to setup this property and restart them. I believe increasing the value should be fine for all existing clients but I want to confirm nothing bad would happen. Thank you Best, Jae
