Subject [jira] [Commented] (SOLR-2927) SolrIndexSearcher's register do not match close and SolrCore's closeSearcher
Date Wed, 05 Nov 2014 17:06:35 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14198657#comment-14198657

Shalin Shekhar Mangar commented on SOLR-2927:
---------------------------------------------

{quote} I synced the trunk code and have some failures.
I don't know how to check for trunk status other that rebuilding it (I did not find an url
where we can check for trunk status)
{quote}

What failures have you seen?

bq. I wonder if it would be better to wait for searcherExecutor shutdown sooner than later
because this thread can keep on doing some work whereas we are supposed to close the core.

Once the searcherExecutor is shutdown, there won't be any searcher thread doing any work (including
warming). The on deck searcher is also closed before we clear the infoRegistry.

> # SolrIndexSearcher's register method put the name of searcher, but SolrCore's closeSearcher
method remove name of currentSearcher on infoRegistry.
> # SolrIndexSearcher's register method put the name of cache, but SolrIndexSearcher's
close do not remove the name of cache.
> so, there maybe lost some memory leak.
