Subject [jira] [Commented] (CASSANDRA-8992) CommitLogTest hangs intermittently
Date Thu, 19 Mar 2015 06:01:40 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-8992?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14368564#comment-14368564
] 

Michael Shuler commented on CASSANDRA-8992:
-------------------------------------------

I tried starting at commit dd84a29, which was the trunk merge of CASSANDRA-7713, and looping
over that commit, the test hung in the same manner on pass #8 and the end of the system.log
looks about the same as the attached one.  I think we have a test problem.

yet, but will have to loop over it to be sure.
