Jeff Griffith updated CASSANDRA-10515:

Killed two birds with one stone here it seems. Looking at he logs before the
commit log growth, it looks like the IndexOutOfBounds exceptions affected all
nodes in this small cluster of 3 at the same time, with with RF=3 that probably
makes sense, doesn't it?

> After upgrading from cassandra 2.0.x to 2.1.10, we began seeing problems
> where some nodes break the 12G commit log max we configured and go as high as
> 65G or more before it restarts. Once it reaches the state of more than 12G
> commit log files, "nodetool compactionstats" hangs. Eventually C* restarts
> without errors (not sure yet whether it is crashing but I'm checking into it)
> and the cleanup occurs and the commit logs shrink back down again. Here is
> the nodetool compactionstats immediately after restart.
