[jira] [Commented] (SOLR-4960) race condition in
CoreContainer.shutdown leads to double closes on cores
[ https://issues.apache.org/jira/browse/SOLR-4960?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13924658#comment-13924658 ]
Nitin commented on SOLR-4960:
-----------------------------
Hi there
I am running 4.3.1 solrcloud and seeing a few of my cores dying with this exception (during reads, writes, recovery etc)
org.apache.solr.common.SolrException; org.apache.solr.common.SolrException: SolrCoreState already closed
solr.log.117-3616225- at org.apache.solr.update.DefaultSolrCoreState.getIndexWriter(DefaultSolrCoreState.java:84)
solr.log.117-3616318- at org.apache.solr.update.DirectUpdateHandler2.commit(DirectUpdateHandler2.java:524)
Could this bug be the root cause of this issue?

> CoreContainer.shutdown has a race condition that can lead to a closed (or closing) core being handed out to an incoming request. This can further lead to SolrCore.close() logic being executed again when the request is finished.
> This bug was introduced in SOLR-4196 r1451797
