each packet has an ID - this is kept in a process buffer - so if a matching
packet comes in, then the server knows its already dealing with that one and
hasnt finished with it...so it marks the new as a duplicate - the cause
for this is often that the backend dealing with a packet is too slow - eg SQL insert
for an accounting packet is often the issue
