Have you checked /var/log/cassandra/output.txt (the packaged install pipes std out/err to there) or the system logs ? If there are no errors in the logs it may well be something external killing it. With regard to memory usage, it's hard for people to help unless you provide some numbers. What do you mean by MAX heap ? Is this the max used heap size reported by JMX or the -Xmx setting passed to the server ?
