             Summary: Support oom hook when running Solr in foreground mode
                 Key: SOLR-9177
                 URL: https://issues.apache.org/jira/browse/SOLR-9177
             Project: Solr
          Issue Type: New Feature
            Reporter: Anshum Gupta


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.
