An example scenario (that is now fixed in Pelops):
Attempt to write a column with a null value
Cassandra throws a TProtocolException which renders the connection useless for
future operations
Pelops returns the corrupt connection to the pool
A second read operation is attempted with the corrupt co
Any idea what's causing the original TPE?

connection is useless for future operations. Pelops was closing connections
when it detected TimedOutException, TTransportException and

Pelops uses a single connection per operation from a pool that is backed by
Apache Commons Pool (assuming you're using Cassandra 0.7). I'm not saying it's
perfect but it's NOT sharing a connection over multiple threads.
Dan Hendry mentioned that he sees these errors. Is he also using Pelops? Fro
