Subject EOFException in ReadStage
Date Mon, 31 Jan 2011 07:09:34 GMT
Version: Cassandra 0.7.1

I am seeing following exception at regular interval (very frequently) in
Cassandra. I did a clean install of Cassandra 0.7.1 and deleted all old
data. Any idea what could be the cause? The stack is same for all the
occurrances.

Thanks,
Naren
