`<div dir="ltr"><div><div>I'm having an issue with r*12 with 10g Solarflare interfaces setup in an aggregate simultaneously dropping for a while for no apparent reason and then coming back. Oddly, I can see them leaving the port channel and dropping on the switch side, but there's no log messages or anything on the client side. They are 5162 cards, for what it's worth.<br><br></div>Has anybody else seen anything like this? Any idea why the host ports don't seem to log any messages to the effect? I can see side affects of this on the host. It only happens during moderate to heavy load. Interrupt balancing looks ok (intrstat), and I watch vmstat, and then all of a sudden the cs, interrupts and other markers drop preciptously (probably as a result of a complete drop of network traffic), and it will stay that way for a couple of minutes and then recover on its own. Sometimes it is up to 30 minutes and then it just recovers, equally as mysteriously. I can sometimes fix it by toggling the interface on the switch. <br><br></div>I have other hosts with the same hardware and driver but running Solaris 10 that don't exhibit this.<br></div>
