In my case, after installing cassandra, as soon as the server is started it hangs on it own (totally unresponsive).
perhaps entirely unrelated, but somebody was asking about lockups on EC2 yesterday and found: http://wiki.apache.org/cassandra/FAQ#ubuntu_hangs

You might want to check your Cassandra logs, they contain important information that might lead you to the actual cause of the problems.

Thanks! But what about the 100% cpu consumption that is causing the server to hang?

I haven't use the packaged kit, but Cassandra uses half of physical memory on your system by default.You need to edit cassandra-env.sh to decrease heap size.Update MAX_HEAP_SIZE and NEW_HEAP_SIZE and restart.

I just installed Cassandra on my ubuntu server by adding the following to the sources list:
deb http://www.apache.org/dist/cassandra/debian 10x maindeb-src http://www.apache.org/dist/cassandra/debian 10x main
Soon after install I started getting OOM errors & then the server became unresponsive. I added more RAM to the server but found that cassandra was consuming 100% CPU & 1GB RAM as soon the server was being started. Why is this happening & how can get it to normal conditions ?
