I have a Cassandra 0.7.0, 3 node cluster with logging set to DEBUG. A few days ago, and I'm not sure what triggered this, the logs started showing messages like DEBUG 17:37:30,399 logged out: #<User allow_all groups=[]> every second or so, regardless whether there was Cassandra activity. Today I just upgraded to 0.7.5, and they're still there. Apart from blowing up the log file sizes, what do these messages mean?
Thanks, Suan
