w and who output is not same

Tue Jul 13 18:17:48 UTC 2004

I have a FC1 system up since 45 days

the 'w' command says 33 users logged in, but shows only 8
where as who shows all 33 users

all of these 33 users are not actually logged in....

finger user-X
shows that user-X is logged in 3 times, which is wrong
he is logged in only once...

what is the problem? (I dont want to reboot!)

Regards,
Jeetu
