Lyuben Todorov commented on CASSANDRA-6699:
-------------------------------------------
I left [a script|https://gist.github.com/lyubent/9184855] running overnight
that runs {{./cassandra-stress write n=1000000 -rate threads=50 -log
interval=10 -mode cql}} and then again in thrift mode. It got through 170
iterations but didn't reproduce. Does this occur rarely or am I just failing to
reproduce it and what commands do you see it with (anything in particular that
pops up frequently)?
p.s. I'm planning to do the same on ubuntu just to make sure.
