Re: Why and How is Cassandra using all my ram ?

you define the max size of your heap (-Xmx), but you do not define the max size of your offheap (MaxMetaspaceSize for jdk 8, PermSize for jdk7), so you could occupy all of the memory on the instance. your system killed the process to preserve itself. you should also take into account that the
