Hi! |

My server hangs every 3-14 days without storing kernel oops message in logs |
| 5 |
(this is dedicated server at hosting, so I've no physical access to console). |
| 6 |
I've set up netconsole, and catch kernel oops by network on second server |
| 7 |
(error message below). |
| 8 |
|
| 9 |
These hangs happens on different kernel versions (current is 2.6.8-gentoo-r3). |
| 10 |
"SpiderAuto" process is my perl script which running using usual user account |
| 11 |
and 24x7 downloading websites (there number (3-7) of such scripts running |
| 12 |
doing parallel download of different websites). |
| 13 |
|
| 14 |
I suppose this is sort of "race condition" error related to huge number of |
| 15 |
simultaneous download requests... |
| 16 |
|
| 17 |
Any ideas how to fix/workaround this error? Maybe try another kernel source |
| 18 |
(I'm usually using gentoo-dev-sources)? |
