Cassandra:The stack size specified is too small, Specify at least 228k

Question

I'm getting this error when starting cassandra after upgrade. Any idea?

# cassandra -f

xss =  -ea -javaagent:/usr/share/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities 
-XX:ThreadPriorityPolicy=42 -Xms1920M -Xmx1920M -Xmn200M -XX:+HeapDumpOnOutOfMemoryError -Xss180k

The stack size specified is too small, Specify at least 228k
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

I have fixed it by editing file /etc/cassandra/cassandra-env.sh

I have changed JVM_OPTS="$JVM_OPTS -Xss180k" to JVM_OPTS="$JVM_OPTS -Xss256k"

and it worked.

Basically the value of parameter Xss determines stack size. As the error indicates, It is too small. Just by increasing Xss will solve the problem. It was 180K before and I have increased to 256K. It can be different in different machines according to the size of database.
