In our production cluster, we observed sudden spike (over 160 MB/s) in read
requests on *all* Cassandra nodes for a very short period (less than a min);
this event happens few times a day.
I am not able to get to the bottom of this issue, nothing interesting in

when taking snapshot, set tag like "uuidgen --time" and use this tag to clear

Jeff,
is it ok to have different values of num_tokens per node in a cluster? won't it
create cluster imbalance? or it better to initiate it on a separate DC?

In a cloud environment, cross_node_timeout = true can cause issues; we had this
issue in our environment and it is set to false now.

Regarding cassandra-stress, make sure that you initiate load outside of

Balaji,
Are you repairing a specific keyspace/table? if the failure is tied to a table,
try 'verify' and 'scrub' options on .91...see if you get any errors.
