Nick Bailey resolved CASSANDRA-8602.
------------------------------------
Resolution: Invalid
So this is just the issue tracker for Apache Cassandra doesn't include tracking
issues for OpsCenter, so I'm going to close this here.
The best way to report issues like this for OpsCenter is via the feedback form
in the OpsCenter interface.
For this particular bug, we are tracking this internally and it should be fixed
in the next major release of OpsCenter. In the meantime, the bug should be
mostly harmless, except for the alarming logging. Thanks for the report though.
