-----------------------------------
Summary: Multiple searchers open for a single core causing memory
issues
Key: SOLR-8663
URL: https://issues.apache.org/jira/browse/SOLR-8663
Project: Solr
Issue Type: Bug
Affects Versions: 4.6
Reporter: Dhritiman Das
For a single core, we are having multiple searchers open. Although the current
searcher points to the latest searcher opened, some old searchers are not
getting cleaned up , they are holding their cache and ultimately causing memory
issues.
Possibly for cores which are taking a lot of time to warmup their cache the
replication interval is overlapping with warmup time taken for the last
searcher open during last replication.
However any idea why sometimes old searchers are not getting freed ?
Ex. Searchers from couple of days back are still seen in Solr console.
ip:port/solr/admin.html#/<core-name>/plugins/core
Is there any known bug around this for Solr 4.6 ?
p.s.: we have custom code extending some Solr components at many places. What I
am trying to understand also is what is the best place to start debugging this ?
