[BusyBox] question about busybox top command

Hey, quick question about the top command.

I am using the busybox-1.00-rc3 on a kernel from DENX  (www.denx.de) which 
is 2.4.24 and running on a mpc8280 home grown board we built.

I tried running the top command and it just seems to hang...  sucking up %100 of the cpu.

I do have the /proc directory mounted(see below).

I can see via another top executable that the "exe" processes starts up...
also ran "strace top" and see llseek/reads just scroll forever...

anyone have any ideas??  do I have something misconfigured??  or did I build
busybox with some missing options??  does the top command require any other options
turned on in busybox?


any suggestions would be helpful.

Bob

# mount /proc so "reboot" works
