I’ve had this problem for a while, and I have no way to diagnose what is going on, but occasionally when system IO gets high (I’ve seen it happen especially on backups), I will lose connectivity with my Fibre Channel cards which serve up fibre channel LUNS to a VM cluster. All hell breaks loose, and then connectivity gets restored. I don’t get an error that it’s dropped, at least not on the Omnios system, but I get notice when it’s restored (which makes no sense). I’m wondering if the cards are just overheating, and if heat sinks with a fan would help on the io chip.


Is there a PCI bridge in the data path? These can often be found on mezzanine or riser cards.

I never thought of that as a possible problem before, but of coarse, it must be a source of possible complications. I never had these problems, though, but interesting for the future! Thanks for that, Richard!
