Subject [jira] [Commented] (SOLR-9177) Support oom hook when running Solr in foreground mode
Date Wed, 14 Jun 2017 23:15:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-9177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16049792#comment-16049792
] 

Chris Haumesser commented on SOLR-9177:
---------------------------------------

With systemd eating the world, more and more people are going to be running solr in the foreground.
As there is potential data corruption that can arise from this bug, and it is a simple fix,
it would be great if someone could take a look at this.

> After reading through the comments on SOLR-8145 and from my own experience, seems like
a reasonable number of people run Solr in foreground mode in production.
> To give some more context, I've seen Solr hit OOM, which leads to IW being closed by
Lucene. The Solr process hangs in there and without the oom killer, while all queries continue
to work, all update requests start failing.
> I think it makes sense to add support to the bin/solr script to add the oom hook when
running in fg mode.
