Houston Putman commented on SOLR-8803:
--------------------------------------
{quote}I can say that in general it is NOT a good idea for Solr to
automatically restart after an OOME... because chances are that the OOME is
just going to happen again repeatedly until the root cause is addressed.
{quote}
Yeah I agree with [~dizzu333] that this is definitely not a general rule, at
least where I have run Solr. OOMs can happen for a variety of reasons, and many
times users would want Solr restarted.
{quote}But the creation of the log files and core dumps just delays the
container restart which leads to less nodes handling the high load, which in
turn leads to a cluster wide crash.
{quote}
This is certainly a tradeoff that needs to be made. Some would want to wait for
the core dumps, some would want a restart faster. So having a toggle makes a
lot of sense.
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? If this is the case, then I am fine having a
variable for SOLR_OOM_ACTION=(exit|crash|script) (I don't like the idea of
none).

> 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.
