Me scared

[MechCD]

I was gone for the weekend, I left me linux box up.

I left Aug 10.
I came back aug 12 around 12:10 PM

The screensaver is locked on the screen, can't ctr;-alt-del or anything. Restart.

Login as mechcd, the CPU usuage is all over the place, no problem, log -out, screen flashes (???) and I'm back at the X login, I do a ctrl-alt-f1 to get to a text prompt. Telinit 3 and then telinit 5.

X login is up again. Login as mechcd. Run g@h. a few minutes later, the screensaver is a black screen with the following written in yellow at the upper left corner
"Segment page fault" (not sure on exact wording)
Wiggle mouse, G@H got to 10% on 18 (18 of 30 10%)
It had stopped with segment fault written right next to the 10%

Then i try to log out, X dies. Try to ctrl-alt-del, kernel panic, try again, can't find kernel and loads of BSODish screens

My root account has some strange system errors in it.... Somethin bout samba can't find service. And Can't rotate logs. There is also a Cron weekly report.
Somethin appears to have gone wrong around 11:52-12:10 at night Aug 11 and aug 12

Worry :eek:

Could a bad WU take the whole system down? i did a -clear and i'm hoping that all it was. :confused: :eek:

I don't think it was a bad work unit.

I had some similar problems with RedHat 7.1 on my firewall for my cable modem a while back.









I would get a segmentation fault and then a core dump. Or, something else and then I would get a kernel panic. I tried all sorts of garbage to get it to work and clean install after clean install did nothing. Tried with and without G@H, same results. And this was a minimally config'd sys, no X-windows, barely any services running.



















I have a feeling that Redhat has a problem with some hardware configurations, because I installed Slackware Linux 8.0 on the firewall and every thing runs just peachy. I didn't change any of the hardware on my firewall, so I'm not sure exactly why it made a diff, but it did. The firewall would have been up for about 10days now if it weren't for the storms I thought were coming through :mad: . And the last time I shut down was because of a network problem. (not mine, the cable company's)









Actually now that I am thinking... I compiled a new kernel on my slackware box after the install. there may be a problem between the default kernel on redhat and your system... If you can get through a compile on your redhat box I would try that. I never could, my firewall would throw a segmentation fault in the middle of a compile every time.









Don't get me wrong, I am not trying to bash redhat, I've used it for the past couple years (off and on) without a problem. I just switched back to slackware because it was the first linux distro I ever tried and I feel more comfortable there.









Anyways I would try recompiling your kernel first.



look here (http://www.redhat.com/support/manuals/RHL-7-Manual/ref-guide/s1-sysadmin-build-kernel.html) for the basics. (if you've never done it before) If you need any more help just drop us a note, (there seem to be a few more linux gurus in the collective as of late).

Take it easy.

[MechCD]

Urgh, kernel compile. I don't know if I wanna attempt that.

I -clear ed the WU and it hasn't done anything else. It may have been a hardware problem because there may have been a T storm around 11-12 that night (when the error occured). Even though I have a UPS on me puter, it may have gotten thrown out of what because my USB printer isn't on the backup, so if the power goes out, Linux freaks out beacuse it can't remount the USB filesystem. (Since when was USB a filesystem?)

:D I can't tell when I did shut down a computer last time, my memory is not that good... :D

Be aware, many of the OpenGL screensavers do crash.....


And take up vital processor cycles.....are you NUTZ? :D

It was Galaxy. use it cuz my APM never werks and the monitor is always on and i don't want it to burn in. I've checked and Galaxy uses at most 1% of my CPU power. Hmmm, i should relace that 1% by makin me 386 crunch

[phil]

1%!!! Man, that is a complete waste of resources...some of our smaller crunchers would kill for that 1% :D

[MechCD]

Ok, lets get offt he screensaver thing here. the real point is I had a major problem and don't have a $%^& clue as to why.

Today I woke up and checked it, the CPU was goin nuts, Full system load an User load was spiking a lot. i closed G@H and it satyed that way. I logged out and back in, and now its not doin' that anymore

As for the CPU cycles, using opera and scrolling uses more than 1% of CPU cycles. I actually use this machine for things other than G@H

???????????????

der me thinks dnar's been dippin in the "special stuff" :D

[MechCD]

Anyone want the log files? I'm to lazy to logout and log back in a few times to post them, but if someone could decipher them (not too hard) I can post them.

Modern monitors don't burn-in... The guns run to cool and color is not like amber or green. Shooting one electron at the screen continuously is what does you in. The retrace is tooo fast and the solid color tooo dim (that's what that dim off-white is for in text mode) to burn a monitor.

The Pixie 21" I'm on right now has been running Linux in text mode for nearly five years, 24/7, with nary a problem... I turned if off a moment ago and held a 1M candle spotlight at an angle to it and couldn't see a single burn-trace...

YMMV, though! [grin]

[MechCD]

Der, I'm a goat, I like my galaxy screensaver..................

I still haven't sent the log files.............. Oops

Windows is worse, can't overclock at all, some 3d games aren't stable at stock settings (1.3ghz)

1.466ghz is obtainable in linux, i think 1.495 is pretty darn stable
