Sylvain Lebresne commented on CASSANDRA-3306:
---------------------------------------------
As I already said, if you are able to reproduce this, please try reproducing
with 1.0.3. And if you are still able to, please attach you system.log with the
exception here because it will have more info on the error that should help.
And if you're not able to reproduce with 1.0.3, then I guess it means we've
fixed it without knowing.
