Likely bump this to 3.0.8; note its caused by a regression in

The default JsonTranscoder does not support byte[] arrays by design. If a byte array is encountered a NotSupportedException with a message is thrown, however, this exception is swallowed and operation does not complete until the Task times out:

System.TimeoutException : The operation has timed out.

For the default 2.5s this doesn't seem so bad, however, if you set the timeout to a longer duration (5 minutes for examples), the code will hang there waiting for the operation timeout so it can continue. This happens here: https://github.com/couchbase/couchbase-net-client/blob/master/src/Couchbase/Core/IO/Connections/DataFlow/DataFlowConnectionPool.cs#L335

Work around: use the LegacyTranscoder
