Does FLUSH TABLES help, by any chance?

Comment by Mihail Karp [ 2013-04-26 ]

yep
flush tables do same think as restart daemon

It might be reasonable then, but I'll forward it to Sergei to confirm (or to see if anything can/should be done about it).

Fixed. Cassandra SE had a feature that would retry failed calls, but it only handled Cassandra's errors errors. Now, it handles network disconnects, also.
