That's max'd out so should be cleared to see if it is continually incrementing.

Port Rcv Errors are the following:
• Local physical errors (ICRC, VCRC, LPCRC, and all physical
errors that cause entry into the BAD PACKET or BAD PACKET
DISCARD states of the packet receiver state machine)
• Malformed data packet errors (LVer, length, VL)
• Malformed link packet errors (operand, length, VL)
• Packets discarded due to buffer overrun

Get the portinfo on the SM peer port. Something like:

smpquery -D portinfo 0,1

assuming you are doing this from the SM node.

Let's see if that's the case first.

So different cables are in use ? Same HCA for OpenSM though ?
