Subject Re: Solr node is out of sync (looks Healthy)
Date Mon, 12 Feb 2018 10:31:17 GMT
Hi Daniel,
Can you tell us more about your document update process. How do you commit changes? Since
it got fixed after restart, it seems to me that on that one node index searcher was not reopened
after updates. Do you see any errors/warnings on that node?

Also, what do you mean by “All nodes are standalone”?
