A Sleeping FreeBSD Box (again).

[nicky]

Hello,

This morning i had another 'sleeping' 6-stable box. I don't really 
understand why it sleeps. I've checked acpi, but i doubt that is it. 
Since at the time when it goes to sleep, it does some heavy processing. 
I don't think it would choose to go to sleep then. The most funny thing 
is, when you go to the console. You press Enter, just Enter, you don't 
login, just punch the Enter button and the box continues where it 
stopped. I typed in 'top' as soon as i could, which showed the table below.

The script commands capture the output of some shells scripts.

last pid: 59391;  load averages: 13.19,  4.43,  
2.70                                     up 14+17:21:56  08:43:04
93 processes:  15 running, 78 sleeping

Is it safe for me to assume that something is hogging my cpu, not 
allowing any other processes to get some cpu time? As a result the box 
does not respond to anything, like pinging?

Or does top has a weird way of showing the cpu times when it has been 
sleeping?

While i still find it rather weird, that pressing Enter seems to solve it.

I hope someone can send some advice or hints my way.

Regards,
Nick
