Mark Miller commented on SOLR-7836: ----------------------------------- bq. and the traces are similar to what was posted before There is not a third thread that has the Writer out? Both of those traces line up with another thread having the writer. I don't spend why they would deadlock each other without another thread involved. I'll take a closer look now that I can duplicate it. I still suspect the proper fix for this is in SolrCoreState. > Possible deadlock when closing refcounted index writers. > -------------------------------------------------------- > > Key: SOLR-7836 > URL: https://issues.apache.org/jira/browse/SOLR-7836 > Project: Solr > Issue Type: Bug > Reporter: Erick Erickson > Assignee: Erick Erickson > Fix For: Trunk, 5.4 > > Attachments: SOLR-7836-synch.patch, SOLR-7836.patch, SOLR-7836.patch, > SOLR-7836.patch, deadlock_3.res.zip, deadlock_5_pass_iw.res.zip, deadlock_test > > > Preliminary patch for what looks like a possible race condition between > writerFree and pauseWriter in DefaultSorlCoreState. > Looking for comments and/or why I'm completely missing the boat. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
