Hello alpha-managers,

this time i've got no useful responses from the list to my question:

> what i see, when entering a `w' from my du-3.2c alpha is (for example):
>
> User tty from login_at_ idle JCPU PCPU what
> aaa r4 xterm1.xaver.mpe 11:01 18:41 3:47 11 - (tcsh)
> aaa xterm1.xav 10:57 -
> bbb qb xterm2.xaver.mpe 18:20 13days -

> I have this corrupted line once for any active Xterminal-session via xdm.

Dave Wolinski <wolinski_at_umalp1.physics.lsa.umich.edu> said, he is seeing
the same features/bugs (?) and thinks that "ntp" may possibly screw up
the idle times.
(We are running xntp too.)

Randy M. Hayman <haymanr_at_icefog.sois.alaska.edu> said, that Digital Unix
has a problem at certain times with updating utmp after a process
exits. He believes that to be a bug.


That was all... :<)

With regards,
