unresponsive system



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


Hi All,

A little while back I was trying to fix a system that was producing a continuous tone after being unused for a while, then logging in.
Now it's running a wee mite slow....

time top -n 1 > output.txt
real 67m42.116s
user 0m0.008s
sys 0m0.000s


Yep - it took it over an hour to run top once and put the output in a file. Then it started beeping again.
I had to hard reboot it (the noise was driving me batty) and guess what - output.txt is nowhere to be found!

I did see the file before I rebooted - cpu was 0%us 0%ni 89%id, swap was 0k used and the first process listed was using less than 2% cpu.

After the reboot it seems to run fine - the software RAID rebuilds etc etc.

I can't seem to nail down what makes it start - I'm not actually using the system at present.
I just set it up to do some testing and it's just sitting there idle.

Any suggestions what's going on here or how to troubleshoot further?

Brian
