The panics you are getting below aren't a lot of info. You'll probably need to build a debug kernel to get crash dump data and examine it further. However, from the fact that it was unable to write buffers back to disk in both cases, I would suggest a HDD problem (I'm going out on a limb here ... but) Also since it's different processes (and the idle process in one case) it seems to indicate flaky hardware. RAM could be the problem as well, but in my experience, HDDs are (statistically) the most likely problem. That's the joy of co-locating. What guarantee do you have that the operating environment is stable? Power fluctuation? A/C in the building is flaky and the temperature get's hot? High humidity at times? Who knows. If it's in your facility, at least you can research these things. Have fun playing detective. -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
