Shawn Heisey commented on SOLR-8145:
------------------------------------
bq. Are people running SolrCloud in production in foreground mode?
I think this is commonly used when users create a service for Windows, but
there isn't an OOM killer script for Windows.
I think that the only time somebody would run in foreground mode on *NIX is
when they are troubleshooting, mostly to see the console logging. I think that
running the OOM killer even in foreground mode makes sense.
A separate question (probably requiring a new issue): Regardless of
foreground/background, should there be an environment variable that can be set
to disable the OOM killer? Like foreground mode, this would be for
troubleshooting.

> I noticed the oom_killer script wasn't working in our 5.2 deployment.
> In the {{bin/solr}} script, the {{OnOutOfMemoryError}} option is being passed
> as an arg to the jar rather than to the JVM. I moved it ahead of {{-jar}}
> and verified it shows up in the JVM args in the UI.
> {noformat}
> # run Solr in the background
> nohup "$JAVA" "${SOLR_START_OPTS[@]}" $SOLR_ADDL_ARGS -jar start.jar \
> "-XX:OnOutOfMemoryError=$SOLR_TIP/bin/oom_solr.sh $SOLR_PORT
> $SOLR_LOGS_DIR" "${SOLR_JETTY_CONFIG[@]}" \
> {noformat}
> Also, I'm not sure what the {{SOLR_PORT}} and {{SOLR_LOGS_DIR}} args are
> doing--they don't appear to be positional arguments to the jar.
> Attaching a patch against 5.2.
