Hi Dan. I'm running on Debian stable and cassandra 0.7.4. I have rows
with up to 1000 columns. I have changed the way I was doing the batch
mutates to never be bigger than 100 columns at a time. I hope this will
work, otherwise the move is going to take too long.

The problem is aggravated by Pelops not retrying automatically and
instead raising a RuntimeException.

I'll try to add a retry if this doesn't work. 

Thanks for your response!
