Could you let me know what's going on at timestamp - 1840:

there's seems to be a great deal of fabric disruptions occuring on the
fibre.  This seems to be occurring on both 22xx ports.  It also
appears that you've set port-down-timeout (dev-loss-tmo) to 0 seconds
(for faster failovers)?

Could you describe the topology?  Would it be possible to isolate the
faults, I take it the constant stream of RESETs are not expected?
