Hello! 1. As far as my understanding goes, there's no such handling of OOM in Apache Ignite that would guarantee not causing cluster crash. This means you should be extra careful with that. This is since after OOM node doesn't have a chance to quit gracefully. Maybe other nodes will be able to eventually remove it, maybe not.
2. It's hard to say what happens here. Can you provide logs?
