Hi, I'm not sure but reading the advisory that just came out today sounds like it could have something to do with your mbuf issues. -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 = FreeBSD-SA-10:07.mbuf

Hi Maxim, I experienced the same issue recently on 8-STABLE branch and it seems it has been fixed since 8.1-RC2 and above. I couldn't track down the root cause in the code nor could I find a commit that seems to be the obvious fix. Thanks, ~ Ali 2010/2/15 Maxim Sobolev sobo...@freebsd.org: Hi,

Hello Jack, We're seeing iffy behavior with igb on FreeBSD 8.0-RELEASE on a new Intel server box (based on their S5520UR motherboard). So far we've seen only oddness with link-state (it wants to always say active, with no cable plugged in, unless we do an ifconfig up/down/up), but I'm concerned

I've dug around in the source repo... it appears the new code is just shy of being MFC'd. Any known caveats with the new code or is it by all accounts good to go? I'm going to try testing it in 8.0. Thanks Charles Owens Great Bay Software, Inc. Charles Owens wrote: Hello Jack, We're

This thread is confusing, first he says its an igb problem, then you offer an em patch :) I have an important rev of igb that I am about ready to release, anyone that wishes to test against a problem they have would be welcome to have early access, just let me know. I am not sure about this

Folks, Indeed, it looks like igb(4) issue. Replacing the card with the desktop-grade em(4)-supported card has fixed the problem for us. The system has been happily pushing 110mbps worth of RTP traffic and 2000 concurrent calls without any problems for two days now. e...@pci0:7:0:0:

OK, here is some new data that I think rules out any issues with the applications. Following Alfred's suggestion I have made a script to run every second and output some system statistics: date netstat -m vmstat -i ps -axl pstat -T vmstat -z sysctl -a The problem had hit us again today
