[CentOS] w stopped working after upgrading procps

Hi

I have just installed a lot of updates on a CentOS 4 box and w appears
to have stopped working -- this machine has 3 or 4 people connected via
ssh, yet this is all that is outputted:

  # w
  20:46:32 up 301 days,  3:21,  0 users,  load average: 0.02, 0.03, 0.04
  USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT

"rpmverify procps" returns nothing so the package hasn't been messed
with.

I don't want to reboot the server -- does any have any suggestions what
could be done to get w working again?

Thanks

Chris
