Subject [jira] [Commented] (SOLR-11297) Message "Lock held by this virtual machine" during startup. Solr is trying to start some cores twice
Date Wed, 30 Aug 2017 17:15:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-11297?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16147624#comment-16147624

Erick Erickson commented on SOLR-11297:
---------------------------------------

Hmmmm, on a quick look I don't see it either. I was looking at this in 6x. I'll look further.
There's a hint in the test where there's something about: getters.add("getWriteLockTimeout");

Anyone have a clue?

> Sometimes when Solr is restarted, I get some "lock held by this virtual machine" messages
in the log, and the admin UI has messages about a failure to open a new searcher.  It doesn't
happen on all cores, and the list of cores that have the problem changes on subsequent restarts.
 The cores that exhibit the problems are working just fine -- the first core load is successful,
the failure to open a new searcher is on a second core load attempt, which fails.
> None of the cores in the system are sharing an instanceDir or dataDir.  This has been
verified several times.
> The index is sharded manually, and the servers are not running in cloud mode.
