[jira] [Commented] (SOLR-12155) Solr 7.2.1 deadlock in
UnInvertedField.getUnInvertedField()
[ https://issues.apache.org/jira/browse/SOLR-12155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16417053#comment-16417053 ]
Mikhail Khludnev commented on SOLR-12155:
-----------------------------------------
Isn't there an exception from the thread which started to load UIF in the log. Overall, it's not really a deadlock (probably it's a livelock), but there is a room for improvement.

> I am attaching a stack trace from our production Solr (7.2.1). Occasionally, we are seeing SOLR becoming unresponsive. We are then forced to kill the JVM and start solr again.
> We have a lot of facet queries and our index has approximately 15 million documents. We have recently started using json.facet queries and some of the facet fields use DocValues.
