Hi @Developer_G_Design

Welcome to the community

No there is no mechanism in elasticsearch that deletes indices on its own / without configuring ILM / DSL or some external script.

So my first question is is your elastic cluster secured with TLS and authentication? And or open to the Internet?

Second, if you're cluster is restarting/ crashing, you need to focus on that.

Perhaps share your setup
