linux

Sorry that I can't be very specific, only symtoms are provided:

Monday morning
a CentOS box, 1GB ram, Pentium 4
web server (thin, rails) does not response (too slow) to a browser of another PC
ping it, ok
ssh into it, ok
a few minutes later, the web server is back to normal speed, serving web requests well
ping it, ok
ssh into it, ok
however, top does not run

what should I look at, about this 'top does not run' symptom? thx
