[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=13695494#comment-13695494 ]

Erick Erickson commented on SOLR-4960:
--------------------------------------

[~[hidden email]] What's the state of all this? These patches look like they're on trunk but not 4x. When I looked at them I realized that the transient and pending lists could be handled the same way (actually in a single list) which simplifies things.

I'll open up a new JIRA for my additions, but we need to merge these changes into 4x before I deal with the next patch....

> 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
