The full sequence of tcp packets from the onset of packet loss and the ACKs (with SACKs) from the remote side should yield some clue why this is happen= ing. This appears to be some kind of SACK (selective acknowledgment) accounting error - but no recent change in this area... --=20 You are receiving this mail because: You are on the CC list for the bug.=
