CARP vs. if_bridge

2010-02-18 Thread Boris Kochergin
Ahoy. I'm seeing what appears to be erroneous interaction between CARP and if_bridge on multiple machines with a variety of Ethernet controllers and architectures. I've observed it on 7.2-R and 8.0-R. The test setup is simple enough: CARP master: FreeBSD t30 8.0-RELEASE-p1 FreeBSD 8.0-RELEASE

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: class=0x0
