inactive system process takes 99% of cpu !!!!

Hi to everyone!!
First of all sorry for my bad english.
If I open the task manager and sort the processes by the CPU column
sometimes appers a SYSTEM process called "inactive system process"
(translated from spanish) which may end up taking 99%, I don´t want to
know how active processes will be ;).
Is this normal?

thanks beforehand

Assuming you could have translated that as "System Idle" ?

From here:
http://www.theeldergeek.com/forum/index.php?showtopic=15731

'The 'System Idle Process' is running when the CPU is doing nothing else, as
this quote from Microsoft shows :-

"A separate instance of this process runs for each processor present, and
has the single purpose of accounting for unused processor time."'
 
Aha your assumption is right, thanks a lot for your explanation.
Weird way the Microsoft way isn´t it? ....

It is not so different from the Unix way for this accounting,
perhaps more visible to casual user though.
 
That´s right all your explanations gave me an idea of what "idle
process" is, I could also learn that its PID is #0, UNIX/LINUX systems
have something alike....so I don´t mind for it no longer don´t I?....

If I type netstat -b what´s my surprise when I note that there is a TCP
connection from my IP to others (That connections are not present always
and can have different IP even different protocols http or https each
time I use netstat) and I can also see its PID is 0 ?!

What does "idle process" want an internet connection for?

I´m gathering all that IPs, and if ask them with nslookup I get no
response from them.

Can you give some new ideas?

Thanks you all
Gracias a todos

I wouldn't worry.

My guess is that you're seeing "connections" that are in the "TIME_WAIT"
state.

These are not active connections - they are simply held there to prevent new
connections from reusing an old connection's stream, and getting leakage
from packets still bouncing around in the network.

Since they are not active connections, they aren't really owned by a
process - in this case, you can read "PID 0" to mean "No PID", rather than
"has a PID whose value is zero".

Alun.

Mmm what you say makes sense
¡ How many things I´ve learnt thanks to the idle process !

Thanks Alun
