Unhappy Redhat stability


Hi, i have redhat 8.0 and im using KDE. I was expecting it not to crash, or at least very rarely, but in the last week or so, it has crashed about 3 times.
The latest crash was when i woke up this morning, i left my computer on over night, got up, ran mozilla and everything stopped. I left it for quite a while incase it was doing something, but nothing happened. Is this normal? Is there any steps i can take to find out why it crashed, and how to prevent it?

Thanks,

CHarlie.

Some dirty written Websites with forwarding or autorefresh may crash Mozilla. This is a Bug of the current mainrelease.

You may update Mozilla to the latest beta.

thanks for replies. the website that loaded was this one, i have it set to my homepage.

good point tho, i have a feeling it was mozilla that i opened the last couple of times, but im not sure. i will wait until it happens again and see if mozilla plays a part.

ok its happened twice since. one time i woke up, tried to run the konsole, and as i clicked the button my computer completely froze. the other time it froze sometime in the night and i woke up to a frozen screensaver.

the only common things between all the crashes in the screensaver and KDE. i will try turning off the screensaver to see if it stops this from happening. has anyone got any other ideas as to why this might be happening?

its not fun having to restart every morning

thanks

CHarlie

At first, my favourite window manager is KDE.
But I've come across some crashes like that in redhat 8.0. Then I changed to GNOME and i find that it's more stable and faster too. Gnome is very much improved in Redhat 8.0. (I mean the version of gnome in redhat 8.0)
You may want to try Gnome.

This sounds like a hardware fault. I've come across this problem with gnome2 and Suse 8 - I thought I had it fixed some time ago but saw it again last night.

I believe it's some wierd interaction between the bios and the kernel, if you have a lot of devices on the same IRQ moving them around may help.

Otherwise file a bug with redhat, see what they think (you may not get a good answer, bugzilla is NOT tech support).

I think it's basically caused by a lockup in hardware somewhere, sorry.

It happens the same to me with almost all "generic" kernels whenever I install a new distro. But I just recompile the kernel and my machine stops crashing.

hey thanks for the replies.

btw if anyone reading this is thinking of getting linux and is put off by my problem, dont be. to prove the stability of linux, i went to an idiots website who opened up 150 pop-up windows on my computer. linux merriily opened them all, and loaded the pages up without moaning to me about insuffient memory or anything, and i was even able to continue using my second desktop and not notice any system lag. closed them all down, and everything is fine. a little while ago i managed to open about 50 windows in windows xp (on the same machine) before it started to moan about a lack of system resources, and i had to reboot to be able to use my computer again cos it was bogged down so much. so to summarise - linux is cool.

It may just be (as was suggested before) your desktop environment. At night when you go to bed, kill X. Then when you wake up in the morning, startx backup and see if everything is happy.

If this doesn't help, try starting "top" before you go to bed, leave it running all night, then whenever it crashes, hopefully at the top of the list will be some suspect hoggin all your resources

Cool

Cool [/B]
Trouble with that is that `top' is mainly CPU oriented (AFAIK, being able to sort by memory usage is a fairly new feature). It sure would be nice to have it be able to sort the processes list by biggest I/O users, who's causing the most page faults, etc. Instead, I'd suggest writing a quick-n-dirty shell script that runs `ps auwx' and `/sbin/swapon -s' every couple minutes and which writes its output to a file. Heck, you could even just stick the command `( ps auwx ; /sbin/swapon -s ) > /tmp/system_status.lis' directly in your crontab. (Can't get much quicker or dirtier than that.) Then after a crash you have some evidence of what was running when the system went down.

I'd be inclined to agree with the poster who suggested that Mozilla was probably the culprit. But I've never seen it hang X when it was unattended. Wonder if the original postier was running anything like gkrellm that'll let you see your swap utilization. Running out of swap is possible if you get large number of browser windows open at the same time. Though, 50 doesn't seem like such a large number. I think I was able to get around 250 open once before the system became pretty much unusable. (One of those ``I wonder what happens if you...'' experiments.)
