Scott Blum commented on SOLR-8145:
----------------------------------
I've always just given this special handling in my own installation. My
bin/solr script is edited to use a specific env var:
{code}
diff --git a/solr/bin/solr b/solr/bin/solr
index 85cd550..0e383b5 100755
--- a/solr/bin/solr
+++ b/solr/bin/solr
@@ -1315,7 +1315,8 @@ function launch_solr() {
if [ "$run_in_foreground" == "true" ]; then
echo -e "\nStarting Solr$IN_CLOUD_MODE on port $SOLR_PORT from
$SOLR_SERVER_DIR\n"
- exec "$JAVA" "${SOLR_START_OPTS[@]}" $SOLR_ADDL_ARGS -jar start.jar
"${SOLR_JETTY_CONFIG[@]}"
+ # scottb: OOMKILLER needs super special handling
+ exec "$JAVA" "${SOLR_START_OPTS[@]}" "${OOMKILLER:=-Dno.oom.killer}"
$SOLR_ADDL_ARGS -jar start.jar "${SOLR_JETTY_CONFIG[@]}"
else
# run Solr in the background
nohup "$JAVA" "${SOLR_START_OPTS[@]}" $SOLR_ADDL_ARGS -jar start.jar \
{code}
Then I just setup OOMKILLER in the calling script to be something like
{code}
'-XX:OnOutOfMemoryError=exec ' + os.path.abspath('killjava.sh')
{code}
At that point, you can get by with a super simple killjava.sh:
{code}
#!/bin/bash
kill -9 $PPID
{code}
The current scheme seems super complicated.

> Project: Solr
> Issue Type: Bug
> Components: scripts and tools

> 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.

> # 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.
