Xorg freezes randomly killing my FreeBSD

[kenorb]

I've got FreeBSD 8.1-"STABLE". My Xorg freezes randomly. Please see the attached pictures where some window is frozen and I can't click anything. I could change terminal to text console, everything was looking fine, apart of that I lost my all opened X windows;(

Then I switched to text console and I did: truss -faep 2878 -o Xorg.truss.out

See here the output: http://pastebin.com/RPvXfyh9

You have output from debugger only when I switched it to X and tried to click couple of times anything, then went back.

Selected probably the most interesting parts:

 2878: write(0,"(WW) fcntl(24, F_SETOWN): Inappr"...,57) = 57 (0x39)

The last command which I executed before pushing the power button, was:
[cmd=]sudo killall -HUP Xorg[/cmd]

It killed my machine completely without any response ;/ My question: Why? ;/

I have six tabs open in opera and it is using about 1/5 of what that top shows opera as using. Do you open new pages in a new tab instead of a new window? And a second trick to try (fixed lockups back in windows98 in browsers)... write a small .sh or something to clear the cache before and after exiting the browser (as of right now, there are 45 opr????? files in the cache directory as I am typing this. Maybe you have hundreds and hundreds of them, too many hours without clearing the cache?) Sorry if it is not due to the browser memory usage, but that would be a first step(s) anyway probably.

I'm using only tabs.

Do you boot Freebsd FreeBSD with the second menu option? Something else to try: install the port "freecolor" and run it every ten minutes or so in an xterm, then if Xorg crashes again, maybe there is not enough free memory (the top of the two bars shown by that port) to restart your shell. (Other issues may apply... overheating graphics card (pci slot cooler...); less than powerful-enough PSU... )

Have you installed xorg with

WITHOUT_NOUVEAU=yes

in /etc/make.conf, and using the ati driver? I've got huge problems with this combination, similar to yours. I read, don't remember where, that it was because xorg is undergoing huge changes lately because of KMS/GEM, and it could make drivers like ati unstable.

The first menu. I've upgraded from 4GB into 8GB, so if it's the memory problem, probably it will sort out this.

> sudo portinstall freecolor
** Port marked as IGNORE: sysutils/freecolor:
	is marked as broken: Does not function correctly on !i386

I'm using NVIDIA, so probably something different.

It happened very rarely and not anymore after RAM upgrade, so keeping this thread as a record if this happen again or somebody will have the same problem.
