That was the first thing tried. No pattern detected at the network traffic or application level, though machines have been known to go down simultaneously (same minute/second) though they service unrelated tasks. No flow control setting changes have been made. I didn't know fast ethernet had reliable flow control.

In article you write: >>fxp0: SCB timeout >>fxp0: DMA timeout >>(repeating) SCB timeout comes about because the chip is refusing to accept any more commands; in this case, it probably is wedged. Is there any pattern to this? Do you happen to have hardware flowcontrol enabled? Does an ifconfig up/down fix the problem? -- Jonathan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
