What was the failure model? CF timeouts? High CPU? Low CPU? JRun queue timeouts?

If it was going on for a longer period the clustering should know one of the instances wasn't responding and should stop directing requests to it (may take some time depending on where the error existed and on how far you tuned the TCP stack). So it is much more likely the instance was actually responding but the response was not what you expected, e.g. empty.
