Ovidiu Mihalcea commented on SOLR-8803:
---------------------------------------
??Just to make sure I understand, the {{-XX:+CrashOnOutOfMemoryError}} option
is not stopping the container from restarting, it is just delaying it because
it has to store the crash state??
So from my tests only, because I couldn't find some definitive documentation
for this in Docker context (or what does "the JVM crashes" actually translates
to in actual signals/facts):
+ExitOnOutOfMemoryError gives me the following message: Docker container exited
with non-zero exit code: 3 (SIGKILL probably)
+CrashOnOutOfMemoryError gives: Docker container exited with non-zero exit
code: 143 (SIGTERM)
So from what I can tell CrashOnOutOfMemoryError aims for a more graceful
shutdown.
However, I don't think that is the preferred scenario in a cluster with a high
replica redundancy count.

Maybe you can remember the reasoning for them? It would really help going
forward with this.

> Solr on windows does not currently have a script to kill the process on OOM
> errors.
> The idea is to write a batch script that works like the OOM kill script for
> Linux and kills the solr process on OOM errors while creating an OOM log file
> like the one on Linux systems.
