Hello, I have 3.3-STABLE kernel on 3.3-RELEASE system.
I have noticed the following behaviour on my system.

If I issue the w command many times the FROM field displays to me the host
from which the users are connected but it happens often that the w output
hangs for some second and instead of the hostname the IP number is
displayed like if the w command is unable to find the hostname
from the IP address

example:

admin@righi 10:59am ~>w
10:59AM  up 5 days, 18:55, 3 users, load averages: 0.39, 0.31, 0.21
USER             TTY      FROM              LOGIN@  IDLE WHAT
admin            p2       suncms.bo.infn.i Tue09AM     - telnet localhost
admin            p4       suncms.bo.infn.i 10:58AM     - w
bsd              p5       localhost        10:43AM     -  (pine)
admin@righi 10:59am ~>w
10:59AM  up 5 days, 18:55, 3 users, load averages: 0.39, 0.31, 0.21
USER             TTY      FROM              LOGIN@  IDLE WHAT
admin            p2       suncms.bo.infn.i Tue09AM     - telnet localhost
wadmin            p4       131.154.11.72    10:58AM     - w
bsd              p5       localhost        10:43AM     -  (pine)

and look that 131.154.11.72 and suncms are the same host from which I Am
right now logged two times.

Why this is happening ?

thanks

Rick
