Mike Schrag commented on CASSANDRA-6103:
----------------------------------------
Just to provide as much info as I can, the entire cluster was stopped. I then
ran a script to start all of them back up at the same time. This particular
cluster is 44 nodes. All 43 other nodes started fine. This one node died at
startup with this exception. After a couple minutes I restarted the one node,
and it came up fine. Priority "Major" is maybe a little aggressive for this one
:)

> This isn't reproducible for me, but it happened to one of the servers in our
> cluster while starting up. It went away on a restart, but I figured it was
> worth filing anyway:
