FC6 Keeps Crashing, cant find problem
This entire problem started a few weeks ago. For about a year, my server was running FC4, and it ran smoothly. I never had any problems. I even left it going during a 2 month vacation and it only coughed once! But around Christmas, the server started crashing. I couldn't figure out why, it seemed to be random, and I didnt see anything abnormal in my logs. So i decided to upgrade to the latest version of Fedora, hoping that would help solve my problem, but it didnt. In fact, it seems to have made it worse.
Heres some quick info about my server:
Intel Pentium 4 CPU 1.80GHz
501.22 MB Memory
40GB Hard Drive
Kernel Version 2.6.19-1.2895.fc6 (SMP)
The hardware is only a year old, so I dont think its a problem with hardware. The server works great after I restart it when its crashed. Theres no boot errors; it boots fine. Right now its running Apache, MySQL, and Samba. Looking through my logs, I cant seem to find anything wrong, so heres a link the entire message log. It seems to me that when it crashes, only some processes stop. For example, once or twice over the last week when its crashed I have been able to access websites that are hosted on the server, but very, very slowly. Could it be the memory? Let me know if there is any other information you need.
Any help is greatly appreciated.
Thanks a lot!
If it was my machine, the first thing I would check is the memory, use memtest. The next thing I would check is the power supply.
i just tried memtest, but i got this message
[root@localhost Sean]# memtest
bash: memtest: command not found
are you sure this is the correct command?
what should i do to ensure my power supply is working correctly?
I'm sorry, my bad.
You'll have to download memtest from here.
To install it, you need to extract it, then compile it.
Open a terminal and login as root, then CD to the directory where you downloaded memtest
extract it with
tar -zxvf memtest86-3.2.tar.gz
Then cd to that directory
Then view the README for installation instructions.
As for the power supply, I would try switching it with a different power supply...or try the power supply on another PC.
Thanks for the speedy reply!
Ok, I installed memtest, but when I run it (./memtest) all it returns is this:
[Sean@localhost memtest86-3.2]$ ./memtest
Is this a good or bad thing?
As for the power supply, unfortunatly I dont have one laying around so I may have to take one out of another computer... I checked the voltage on it using a volt meter, and its out putting just below 5 v, so thats about right.
And if ur processor is not multi-core, u can even try disabling SMP support on ur kernel...

From the Fedora website
Default Kernel Provides SMP
There is no separate SMP kernel available for Fedora Core 6 on i386, x86_64 and ppc64. Multiprocessor support is provided by the native kernel.
EDIT:that wasn't the correct link. I deleted that and changed it to this.
I followed that guide, and everything goes fine until I get to the step where they ask you to run (Step 3)
rpmbuild -bp --target=$(uname -m) /usr/src/redhat/SPECS/kernel-2.6.spec
[root@localhost Sean]# rpmbuild -bp --target=$(uname -m) /usr/src/redhat/SPECS/kernel-2.6.spec
bash: rpmbuild: command not found
Am i running this right?
