My server crashed twice with same Oops info. It runs apache,mysql,nfs |
| 2 |
(client only), it has more than 2GB swap partition (does not use it |
| 3 |
very much), 2GB ram, disk is Raptor on SATA... |
| 4 |
I have two clones of this machine (computers with same parts, system |
| 5 |
is copied by RSYNC) and only one of them has these Oopses. I made |
| 6 |
copies of gentoo like this: |
| 7 |
|
| 8 |
1 -> 2 -> 3 |
| 9 |
|
| 10 |
...and that one which crashed is "2", so if there was any error |
| 11 |
durring rsync from 1->2 it should be repeted on "3", but "3" and "1" |
| 12 |
works all the time without any crashes. |
| 13 |
|
| 14 |
When it crushes some process' just stops - for example ps ax stopped |
| 15 |
in the middle of list, ctrl+c did not helped, w (/bin/w) did not |
| 16 |
showed anything, but dmesg worked and I could login thourgh ssh to try |
| 17 |
another command. |
| 18 |
|
| 19 |
The server must work all the time... |
