Did you check nodetool status and logs? If so, what is reported?

Regarding that more and more memory is used. This might be a problem with your table design.
I would start analyzing nodetool tablestats output. It reports how much memory (especially
off heap) is used by which table.

What are minimum and recommended ram and space requirements to run Cassandra in AWS?

Every like 24 hours Cassandra stops working. Even though the service is active, it’s dead
and non responsive until I restart the service.

Top shows %MEM slowly creeping upwards. Yesterday it showed 75%. 

In the logs it throws that Cassandra is running in degraded mode and that I should consider
adding more space to the free 25G...

Thanks in advance for your help. Newbie here... lots to learn.
