Hi All,

I am using SOLR 7.5 version with master slave architecture.
I am getting :

"PERFORMANCE WARNING: Overlapping onDeckSearchers=2"

continuously on my master logs for all cores. Please help me to resolve this.


Thanks & Regards,
Akreeti Agarwal

Re: SOLR 7.5 Performance WARN

Hi Akreeti,

The "onDeckSearcher" count is the number of searchers that are
currently being opened/warmed for a given core.  New searchers are
opened by (some types of) commits.  So essentially, what this message
means is that you're asking Solr to do commits so close together that
commit N is happening before commit N-1 has even finished.

The fix usually is to commit less frequently.  Are you triggering
explicit commits via the API (or through SolrJ)?  How frequently do
the settings in your solrconfig.xml have you committing?

Hope that helps,

Jason
