-----------------------------------------
Summary: spurious ERRORs due to race condition between
SolrIndexSearcher metrics and IndexReader closing
Key: SOLR-14657
URL: https://issues.apache.org/jira/browse/SOLR-14657
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Chris M. Hostetter
Assignee: Chris M. Hostetter
I've seen situations in the wild where systems monitoring/polling metrics can
trigger scary looking - but otherwise benign - ERRORs due to
AlreadyClosedExceptions if/when the searcher/reader is in the process of being
re-opened and the Gauge tries to call reader.numDocs(), etc...
We should tweak the metrics logic to just ignore these exceptions
