Timothy Potter updated SOLR-6106:
---------------------------------
Attachment: SOLR-6106_prelim.patch
This is just a preliminary patch to help troubleshoot this issue if it comes up
again (little more logging in a few places). There's definitely something very
wrong here as I see the following events in my log:

I also noticed that the ManagedResourceStorage could get the path it needed
from the ZkSolrResourceLoader, so this patch fixes that as well.
