If every node is a replica it sounds like you've got hardware issues. Have you compared iostat to the "normal" nodes? I assume there is nothing different in the logs on this one node?Also sanity check, you are using DCAwareRoundRobinPolicy?
Thanks for the answer, I had to concentrate on other things for a few days, I'm back to that problem.
The PHP Driver call is :$cassandrabuilder->withDatacenterAwareRoundRobinLoadBalancingPolicy("mycluster", 0, false)->withTokenAwareRouting(true)->withSchemaMetadata(true);
After that, the call is done like this : $result = $cassandra->execute(new Cassandra\SimpleStatement($query));$cassandrasession->executeAsync($this->queryPrepared, array('arguments' => $values));
Could the async call put too much pressure on the server ? Calls from 11 client machines.
Thanks !
