wrong output of "who" and "finger"

[Burba, Viktor]

Dear GNU team,

I have a problem with output from "who" command. As you can see below

busdm:~ # who -u
root     pts/0        Nov  2 15:56   .         21861 (192.168.0.20)
root     pts/6        Jun 18 13:04   ?         15579 (10.11.20.1)

busdm:~ # uptime
  4:06pm  up 3 days  2:19,  2 users,  load average: 0.42, 0.30, 0.16
busdm:~ # date
Mon Nov  2 16:07:04 CET 2009


"who" shows me users logged in from Jun18, even so the host has been rebooted 3 
days ago and today's date of the host is 2nd Nov. Also there is no PID 15579. 
Can you please explain this weird behaviour?



Best regards,
Viktor Burba
