System Freeze with RedHat 9.0
 
Today and yesterday, my system completely froze (nothing moved, no Input/Output possible - just a complete freeze), yesterday at 09:36 am and today at 08:29 am (that's what the desktop clock said).
Here's what I got out of /var/log/messages, for yesterday:
Code:

Uhm... anyone knows what exactly causes this? - I kinda don't have any clue about what those messages say...

I'm using RedHat 9.0.

Thanks & bye bye~,

Woooh....that's some "xyz pqr abc" letters only someone specialized at Redhat can talk of.
Being a redhat 9 user, I wud like to know, what was the last operations you performed before the time, the first error occured. Looking at the kernel version (2.4.20-31.9) I think it is unstable (as per kernel number notations). Secondly, the word "paging" request, indicates a problem of invalid reference to the memory at location fb7a4ae0, thereby suggesting that some memory location has some errors. Try using a software that wud check your memory for errors.
I am not sure of this solution, but that cud be one of your options

MHOOO 04-08-2005 08:03 AM
The last operations before that error?
Well... I suppose there were quite a few - but the only major ones, were the Installation of the SMART Utility (through a RPM Package) and a check of my HDDs using that Utility.
Do you maybe know a Linux Software that could check my memory for errors?

redhatrosh 04-08-2005 01:04 PM
I dont actually remember well, but u may boot your Linux using the installation CD and check for options in it. U may have a software for checking errors.

MHOOO 04-23-2005 05:17 AM
Well - I've checked the RAM with `memtest86` and I didn't get any errors.
But I still get these Freezes... nobody here who might know what the cause of this is?
Is there a possibility of the swap-space being the cause of this?
