Subject [jira] [Commented] (SOLR-7836) Possible deadlock when closing refcounted index writers.
Date Thu, 13 Aug 2015 15:17:46 GMT

    [ https://issues.apache.org/jira/browse/SOLR-7836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14695341#comment-14695341

Erick Erickson commented on SOLR-7836:
--------------------------------------

[~markrmiller@gmail.com] I _thought_ everything was in the two zip files I attached a couple
of days ago, what did I miss? See my comments two days ago for the provenance.

BTW, I'll be intermittently available today and not at all tomorrow (business hours CA time)
if you'd like to chat.
