Sorry for crossposting, but I wasn't sure which mailing list was the most appropriate for this email. I have an application pulling about 220Kpps from a bce(4) card (details below). At what seems to be random times, errors start showing up on that interface (I'm watching it with netstat -w1 -I), so about 10% of the initial 220Kpps is reported as errors. Bringing the interface down and then back up clears the errors, but they do reappear at a later time. Before they reappear, the systems manages to pull the full 220Kpps as before. This is a temporary setup, we'll very soon use an Intel fiber card, but I thought this issue was worth mentioning, as I don't think it's a hardware problem (the switch also reports no errors). The system is running a fresh (yesterday's) RELENG_7. The card is onboard, on a HP DL380 G5. Here's the pciconf output: -- cut here -- pcib13@pci0:2:0:0: class=0x060400 card=0x00000000 chip=0x01031166 rev=0xc3 hdr=0x01 vendor = 'ServerWorks (Was: Reliance Computer Corp)' device = 'BCM5715 Broadcom dual gigabit, pci bridge' class = bridge subclass = PCI-PCI bce0@pci0:3:0:0: class=0x020000 card=0x7038103c chip=0x164c14e4 rev=0x12 hdr=0x00 vendor = 'Broadcom Corporation' device = '5708C Broadcom NetXtreme II Gigabit Ethernet Adapter' class = network subclass = ethernet -- and here -- Regards, Vlad -- ~/.signature: no such file or directory
