Hi Community,

Can anyone give me some pointers where to look, or start to look for where this 
issue is coming from?


On startup I get this in the logs and my service goes into a failed state. 
Active(exited)

Any pointers would be handy as NULL exception is very hard to investigate.

Cassandra 3.0.11, on linux 7.3 (vm)
