Jack, I think the SCP scenario would be easiest for anyone else to reproduce. If you need a different type of scenario, let me know. I can't put this box into heavy use until I figure this out, so you might as well use me as a guinea pig. Thanks, ==ml On Wed, Jul 20, 2011 at 10:18:32AM -0700, J

Hi, I'm not seeing a complete stall, just very slow performance. I have two hosts on a shared gigabit Ethernet. One is OpenSolaris, the other FreeBSD. My SCP from the Opensolaris box to the FreeBSD one goes at: 653 MB00:29 The FreeBSD machine is an Intel SS4200-E. I have a second environm

It stalls on just a basic file scp. Our current test is to scp the freebsd iso to the machine. It won't always do it but it does "seem" like once its had one stall its very much more prone to repeat stalls. Here are some examples of what we see:- FreeBSD-8.2-RELEASE-amd64-disc1.iso41% 2

Did you eliminate that 7.0 box as part of the issue? Meaning switch to say a Linux or 8.2 partner to see if the problem persists or stops? Cheers, Jack On Wed, Jul 20, 2011 at 10:02 AM, Steven Hartland wrote: > ** > Apologies, thought it might be worth a shot, but clearly not thanks for > clar

Apologies, thought it might be worth a shot, but clearly not thanks for clarifying :) You absolutely correct with the msix masking the issue, we've just this minute had it stall again even with MSIX disabled :( I agree we have many machines using igb and em without issue even under lots of loa

This is an em bug, igb does not share interrupt code with em, furthermore the adapter the filer of the bug is using doesn't use MSIX, only one type in the em driver does, and I might add lots of heavy users on that adapter have MSIX on without issues. I believe turning MSIX off is just masking wha

We're seeing tcp stalls under igb under 8.2-RELEASE and 8-STABLE (which shares some code with em) and the workaround for use is currently adding the following to /boot/loader.conf hw.igb.enable_msix=0 Might be worth trying that. Regards Steve - Original Message - From: "Michael W
