No, I don't. Do you have any more information? What is your code doing
when it fails? Just issuing a regular query? Are you using any of the
less common driver features: Large objects, fastpath api, a COPY patch?
If the driver had a protocol problem I would expect it to be rather
repeatable. If the driver had a synchronization problem it should have
disappeared when you moved to a single thread model. I've attached the
test script I've used to try and beat on the driver.
