I agree to an extent, but the pathological case is acutely painful. It could mean an irrecoverable cluster, and tracking down the reason would be challenging. > debugging Do you think preserving the count helps here? Between the count as an indicator of a problem and logs to dig deeper, i can't see any loss in signal. - Bill ----------------------------------------------------------- This is an automatically generated e-mail.
