I'd say that is the reason you are running out of memory.

Why did you increase the stack-size to 5.5 times greater than recommended?
Since each threads now uses 1000KB minimum just for the stack, a large
number of threads
Correction, there was a typo in my original question, we are running cassandra
1.1.10
Thanks and sorry for the inconvenience.

1.1.0 has significant issues, including non-working Hinted Handoff.
Also, OpenJDK is not officially supported.
Upgrade to 1.1.11 and Sun JDK.

Since last night I am seeing CPU load spikes on our cassandra
boxes(Occasionally load goes up to 20, its a Amazon EC2 c1.xlarge with 300
iops EBS). After digging around a little I believe its related to heap
memory and flushing memtables.
