Hello,
I did schema update to Solr cloud of Source CDCR cluster and same on
target. After Collection Reload, noticed "error opening searcher" /
IndexWriter closed etc. on leader node while all replica's went into
recovery mode.
Later after restarting Solr on Leader noticed below too many file open
errors. The ulimit shows unlimited.
What could have gone wrong above/and how can we avoid. This is with 6.6.2
and there were ingestions/delete and searches happening the time I reload
the collection.
Caused by: org.apache.solr.common.SolrException:
java.io.FileNotFoundException:
