Ah.. Thanks for the great tip!

I tried decreasing it and tried various combination (including the one you
have suggested) but I am still getting the same error message. Following is
the /prop/meminfo on the machine that I am using.

I have made sure that the cassandra.in.sh that I am editing is actually
used... I've installed a new VM with Ubuntu 9.10 and I was able to recreate
the same issue on Ubuntu as well. The machine that I am having this issue is
RHEL5.

What else can I try to resolve this?
