Description

This bug is reported by a customer. Whenever they issue a rebalance(after removing a node from the cluster or add a new node), client operations(PHP - sample code attached) time out with the error below

PHP Warning: Couchbase::set(): Failed to store a value to server: Operation timed out in /root/test_worker.php on line <n>

This issue is consistent for both the customer as well as our in-house reproduction in Support. There are no errors on the server side. Rebalance does complete. And once rebalance is complete, the same script runs fine without any errors.
