I had trouble running repair. It seems there is an installation issue with Cassandra. Over enough times running repair, things seemed to work okay once I ran repair over the weekend. I don't know the root cause, though. The Cassandra logs don't reveal much detail as to any IO errors or not. My suspicion is there is either a capacity or load issue, but since this happened as well with 4.9, I'm guessing not an RHQ issue. |

Seems to have happened when I got some timeouts at startup. Startup took a long time, so I wonder if there is some sort of conflict. The error message looks really suspicious, though.
