Hello.
Any messages about GC earlier in the logs? Cassandra server monitors
memory and starts complaining in advance if memory gets full.
Any chance you've got a full key delete-only scenario for some column
families? Cassandra has a bug not being able to flush such memtables.
I've filled a bug with patch on the issue.

Hello,
We have a 6-node ring running 0.8.6 on RHEL 6.1. The first node also
runs OpsCenter community. This node has crashed few time recently with
"OutOfMemoryError: Java heap space" while several compactions on few
200-300 GB SSTables were running. We are using 8GB Java heap on host
with 96GB RAM.
I would appreciate for help to figure out the root cause and solution.
