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.
