Subject [jira] [Commented] (DERBY-5643) Occasional hangs in replication tests on Linux
Date Tue, 20 Mar 2012 23:21:39 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5643?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13233935#comment-13233935
] 

Knut Anders Hatlen commented on DERBY-5643:
-------------------------------------------

I mentioned in an earlier comment that the compatibility tests in Oracle's nightly test runs
had problems after the fix went in. That wasn't quite true. When looking closer at the test
reports, it turned out it was suites.All that had problems. It looks like it got stuck in
the replication tests on all platforms except Windows. And the tinderbox has hung in a similar
state since Thursday (it did however run successfully twice after the fix for this issue was
checked in, but I have no doubt it was the changes in this issue that caused the problems).
I haven't been able to reproduce these hangs in my own environment yet.

The nightly tests haven't run with the latest fix for this issue yet, because the Svn EU mirror
was down when the tests were supposed to start last night. Looks like they're running now,
and so far two Solaris platforms have completed their suites.All runs - http://dbtg.foundry.sun.com/derby/test/Daily/jvm1.6/testing/Limited/testSummary-1302996.html.
Not sure if that means the problem is fixed, as it appears to be intermittent. I guess we
know more in a couple of hours when the results from the other platforms appear.
