-------------------------------------------------------------------
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.
