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.</span><o:p></o:p></p></div></div></blockquote><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Is there a PCI bridge in the data path?
