[SlugBug] server health

[Bill Best]

hi

i have a server below and here's the output of top:

> 1:40pm  up 266 days,  4:50,  1 user,  load average: 0.00, 0.00, 0.00
> 56 processes: 55 sleeping, 1 running, 0 zombie, 0 stopped
> 
> CPU0 states: 23.0% user, 76.0% system,  0.0% nice,  0.0% idle
> CPU1 states: 22.0% user, 77.0% system,  0.0% nice,  0.0% idle
> 
> Mem:  1036048K av, 550288K used, 485760K free, 21512K shrd, 185188K buff
> Swap: 2048248K av,    184K used, 2048064K free            296524K cached

what concerns me is that it the processors are 0.0% idle - i take this 
to mean that the CPU's are working flat out.

this is a Dell PowerEdge 1550 server with dual PIII 1 Ghz processors and 
  1 GB of RAM - this used to be quite a bit, back in the day.

i wouldn't have thought that there was an issue with the RAM as so 
little swap is being used.

should i be thinking of upgrading the processors or, dare i say it, 
should i be thinking of rebooting the machine?

i looked at ps aux but nothing there gave me heart failure and sorting 
top with CTRL+M looked ok too.

i could try stopping and starting the busiest processes but i thought 
i'd run it past here first.

many thanks
