We're suddenly seeing a fair number of exceptions like one below. Thought
the root cause is failing session affinity in our clusters, but the
exceptions persist even after we shut down all but one host behind HAProxy.
I realize the question is somewhat ambiguous, but what - besides lack of
session affinity - can be some other causes of these exceptions?
thanks
