I get the following errors every 30 minutes between 2 of my fibre channel switches:
A fibre channel port changed its operational state, Port 18 (12) changed operational state to Online
A fibre channel port changed its operational state, Port 10 (a) changed operational state to Online
A fibre channel port changed its operational state, Port 18 (12) changed operational state to Offline
A fibre channel port changed its operational state, Port 10 (a) changed operational state to Offline
Any ideas on troubleshooting this?

Do you use DCFM 10.3.x ?
If yes, set the fabric to "unmonitored" or stop the DCFM-Server for few hours.
If the offline/online errors are gone then upgrade to 10.4.0.
There is a nice bug described in the releasenotes.

But the looks of it what ever you have plugged into port 17 & 18 has an issue.
Try and change the SPF's in the switch and in the HBAs (if you can swap them out)
Clear the stats on the two ports with the following command.
And keep monitoring it.
