Subject Re: What does refCount denotes in solr admin
Date Thu, 18 Aug 2016 08:50:53 GMT
When instance is idle you should see refCount=2 in solrAdmin. One count
goes from coreContainer holding a core instance until reload and two comes
from solrAdmin request which opens a core while it renders response. So,
until you don't request this stat the refCount is 1 that somehow remind
quantum mechanics.
Seen refcount 171 either mean 169 parallel request, which hardly make sense
and I suggest to shrink the Solr container thread pool or/and tweak a
client app. But If it keeps growing and remains >2 even when instance is
idle, it means some plugin leak it - avoid to close/decref solr core.
Hope it helps.
