Hi Peer, I changed cassandra-env.sh and following are the parameters I used,'
MAX_HEAP_SIZE="8G" HEAP_NEWSIZE="1600M" But I am still unable to start the server properly. But this time system.log has bit different logs. https://gist.github.com/cdwijayarathna/75f65a34d9e71829adaa Any idea on how to proceed?
