Hi,
I'm administering a (remote) server; and just got a partial lockup... dmesg gave me this:

How bad is this? I tried (remote) rebooting; but the shutdown proces just crashed: | Code: |
root 7327 0.0 0.1 1544 596 ? D 19:31 0:00 shutdown -r 0 w
|
Anyone some ideas? Especialy on the cause;
And maybe a solution? (I only have SSH access; so "press the reset button" won't do) |

It's a kernel panic - no way out except the big red button.
And yes, it's serious - either you have some bad RAM or you have messed up something in your kernel config.
How long has this box been running without any errors (that last is important!) ?

It has been running for weeks; without a single issue (in dmesg)
I just tried a "cp /var/www/... /tmp/..." and it suddenly hanged.
Bad ram can be a posibility; but I ran memtest86 on it and it didn't report a single error... |

it's gray; but anyway. Isn't there a way to convince the processor to reset (unign linux-commands)? just RESET, without shutting down anything at all? |

it could also be a kernel bug or a hardware hiccup. unfortunately as you chose not to compile any debug symbols into your kernel, nobody will be able to tell which area of the kernel started the crash
i'd suggest you upgrade to the latest kernel and compile in debug symbols incase it happens again
