Subject [jira] [Commented] (LUCENE-4241) non-reproducible failures from RecoveryZkTest - mostly NRTCachingDirectory.deleteFile
Date Fri, 20 Jul 2012 19:15:36 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13419459#comment-13419459

Mark Miller commented on LUCENE-4241:
-------------------------------------

Yeah, I'm not ruling it out either - I try to be very careful before filing lucene bugs based
on replication stuff and solrcloud especially (with all its jetty killing and what not). But
I seemed to be able to cause the same situation with an isolated test (im not tripping the
same assert, but causing a different exception in close because of the same invariant). So
I'm somewhat sure it's a real issue with the dir, but since I don't have a fix, I don't know
for sure. I tried just over syncing by synchronizing every method in that dir, but no luck
:)

> Since getting my new laptop, i've noticed some sporadic failures from RecoveryZkTest,
so last night tried running 100 iterations againts trunk (r1363555), and got 5 errors/failures...
> * 3 asertion failures from NRTCachingDirectory.deleteFile
> * 1 node recovery assertion from AbstractDistributedZkTestCase.waitForRecoveriesToFinish
caused by OOM
> * 1 searcher leak assertion: opens=1658 closes=1652 (possibly lingering affects from
OOM?)
