[jira] Commented: (ZOOKEEPER-684) Race in LENonTerminateTest

["Flavio Paiva Junqueira (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-684?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12842068#action_12842068 ] 

Flavio Paiva Junqueira commented on ZOOKEEPER-684:
--------------------------------------------------

The race we observe in the log attached should only happen if the socket times out after 200ms in LeaderElection.java. In regular runs, I wouldn't expect it to time out, but on a very slow machine it could happen. If we start observing it often, we might consider increasing the socket time out value to avoid false positives. 

For now, my recommendation is that we don't fix it.

> testNonTermination failed during a Hudson run for ZOOKEEPER-59. After inspecting the output, it looks like server is electing 2 as a leader and leaving. Given that 2 is just a mock server, server 0 remains alone in leader election.
