[jira] Commented: (ZOOKEEPER-513) C client disconnect with stand-alone server abnormally

This probably indicates that the server went down (the process wasnt running). Qian, As pat mentioned, can you upload the server logs during this time?

[jira] Commented: (ZOOKEEPER-513) C client disconnect with stand-alone server abnormally
[ https://issues.apache.org/jira/browse/ZOOKEEPER-513?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=12746981#action_12746981 ] Patrick Hunt commented on ZOOKEEPER-513: w/o the zookeeper server log it will be difficult to determine. please attach the server log from the time you saw the issue. It looks like you are running standalone server on localhost? Perhaps your machine is swapping or doing heavy IO and the server was unable to respond in time? You are using a very low timeout of 2 seconds, which means that if the server doesn't respond w/in 0.6 seconds the operation will timeout. My best guess is that the timeout is due to this (we've seen it before, esp in cases where ppl used vms - ie vmware, on over-virtualized system).
