Hi, In the end it turned out to be a bad switch. We replaced the switch hardware and stats are now clean. Cheers Joe ----------------------------------- originally --------------------------------------------------------------------- Got a 6900, 48CPUs, Solaris 10 118833-36. A couple of weeks ago we added in a second pair of NICs with a view to segregating NFS traffic on one subnet from the rest of the prod network. The machine has 4 cassinis (ce), one pair on 150 subnet and one pair on 152. IPMP one both pairs is active/standby. Netmasks are fffffe00. Card speeds are 1000Base. Under periods of heavy load we see high retransmission/duplicate packet rates. Clients are mostly v490s with ce cards running at 100Base. The issue only seems to have appeared since we added in the extra cards. Can anyone suggest places to look for possible cures? I'm wary of tuning the stack initially but it remains an option.
