Shawn Heisey commented on SOLR-9168:
------------------------------------
I thought I had made this comment already, but it's not here, so I'll try again.
Watching the exit code of the following command will determine whether the flag
is supported without any need to parse a version string (POSIX version shown)
{noformat}
$JAVA -Xmx1M -XX+ExitOnOutOfMemoryError -version > /dev/null 2> /dev/null
{noformat}
If the flag is supported, it can be combined with OnOutOfMemoryError calling an
oom logging script. If it's not supported, then we just use the existing oom
killer script.
I'm not sure whether the -Xmx parameter is required with -version to keep
memory usage down.

> Right now the start script always uses $SOLR_TIP/bin/oom_solr.sh to handle
> OutOfMemoryException. This script only kills instance of solr.
> We need to do some additional things (e.g sent mail about this exception)
> What do you think about adding possibility to set up own script?
> Proposition:
> {code}
> if [ -z "$SOLR_OOM_SCRIPT" ]; then
> SOLR_OOM_SCRIPT=$SOLR_TIP/bin/oom_solr.sh
> fi
> [...]
> nohup "$JAVA" "${SOLR_START_OPTS[@]}" $SOLR_ADDL_ARGS \
> "-XX:OnOutOfMemoryError=$SOLR_OOM_SCRIPT $SOLR_PORT $SOLR_LOGS_DIR" \
> -jar start.jar "${SOLR_JETTY_CONFIG[@]}" \
> 1>"$SOLR_LOGS_DIR/solr-$SOLR_PORT-console.log" 2>&1 & echo $! >
> "$SOLR_PID_DIR/solr-$SOLR_PORT.pid"
