Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

When these masseges occurs "free -m" was like below:
total used free shared buffers cached
Mem: 1008 991 16 0 149 381
-/+ buffers/cache: 460 547
Swap: 1023 4 1019
These kernel messages could be memory related? If so is it because of memory fault, or low memory? What should i do? Do i need add extra memory to system or memory check.
If it is not related memory, then what would you suggest?
After these kernel messages some processes begins to defunct one one by, and then machine crashes.
In order to prevent crash i regulary reboot machine once in 2 days.
Here is some info about system:
This box is used used as a mail , web and mysql server. There are over 100 hundred web and mail hosts. And mails scanned with qmail-scanner and ClamAV.
Kernel : 2.4.22
I'd say the box probably does get pounded from your description. What kind of RAM is it, how fast a machine? How big of swap? And yes, more RAM never hurts. It probably wouldn't hurt to do some memory tests as well on this machine.
