Do you see a lot of those, or only few during a small interval ? Same quest=
ion
the timeout exceptions ?
You could get a few of these messages the time it takes to the node to
figure out
to which version they are talking. This should be fairly quick tough.

As for the timeouts, what is your replication factor and consistency level =
for
the inserts and did you update only one node at a time ?
