Evaluating the performance of membase cluster
As a part of engineering requirement in our organization, I am evaluating the performance of various cache management systems.
Currently I have 3 nodes in the cluster running Membase server version 1.7.0. and spymemcached 2.7.3 client.
I am currently noticing some exception like these when the concurrency on the client side is high. The same operations succeeds if the concurrency is low.
2011-11-07 21:43:08.478 WARN net.spy.memcached.protocol.binary.BinaryMemcachedNodeImpl: Operation canceled because authentication or reconnection and authentication has taken more than one second to complete.

SEVERE: Get for key:0000000000900787 returning null
java.lang.RuntimeException: Exception waiting for value
Can someone please help me with this.
