Ruby Client does not handle the timeout appropriately

This is the problem that the customer is encountering
(Ruby code coming up):

Timeout::timeout(2) do
couch_client.get(key)
end

But we are seeing Couchbase::Error::Timeout exceptions being raised. I know the default timeout for the Couchbase client gem is greater than 2 seconds, so I'm wondering: what could cause Couchbase to return a timeout (0x16 error code) before it actually has time to timeout?

The complete ruby source code is attached , Please take a look at it.

------
support's analysis:
 The client is not timing out fast enough it should time out in 2.5 sec or something but instead it's waiting a long time.
