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.

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.

One of my servers is running unusually high loads, with out any valid reason. this was noticed after the server was hard rebooted after it got hanged. i am running apache and sendmail primarily on the server.
yes i have use top to find out, but i see only httpd.... which is not putting much heavy cpu load.... around 0.4 % cpu. but the load averages from uptime are in the range of 20 to 40 which is extremely high.
further the site on apache is very slow.......
this is something i really do fail to understand!!!!!
plz tell me what is going qrong and where do i look for it!!!!
Location: Rome, Italy ; Novi Sad, Srbija; Brisbane, Australia
Distribution: Ubuntu / ITOS2008
Im not sure if this will be of any help, but maybe you should chech /var/log/messages , /var/log/secure , /var/log/syslog and look around the date and time when the server hanged the first time and see if the logs give any clue of what might have hanged the server and if something is wrong.
