I too have seen the out of sequence response problem. My solution has just been to retry and it seems to work. None of my mutations are THAT large (< 200 columns).
The only related information I could find points to a thrift/ubuntu bug of some kind (http://markmail.org/message/xc3tskhhvsf5awz7). What OS are you running?

I'm having trouble while inserting big amounts of data into cassandra. I'm getting this exception: batch_mutate failed: out of sequence response I'm gessing is due to very big mutates. I have made the batch mutates smaller and it seems to be behaving. Can somebody shed some light? Thanks! No virus found in this incoming message.
