Do we need dump the memory when OOM occurs？

Do we need dump the memory when OOM occurs？

The dump file maybe too big and disk space may be not enough to store it. So users should specify the path to store it.

+1 from my side. oom dump should be an opt-in feature. The bin/start-shuffle-server.sh may handle that as a cli argument or env variable.

Good idea. This should be supported.
