Nothing here, all is similar to other system. And historically, |
| 56 |
this system has not had this problem. I'm not certain when it started: |
| 57 |
|
| 58 |
$ w |
| 59 |
14:39:25 up 3:23, 1 user, load average: 1.00, 1.00, 1.00 |
| 60 |
|
| 61 |
|
| 62 |
It looks more like corruption in the application binary to me. |
| 63 |
When have you ever seen a system at all three timing interval |
| 64 |
locked at 1.00 when a system is quiescent? |
| 65 |
|
| 66 |
What package is top part of? |

I do not suspect a 'hack' is involved, because if I pull the ethernet |
| 74 |
cable, it does not effect the load (still at 1.00). |
