Package: procps
Version: 0.97-4
Here is an example of some bogus output from top. Notice the second
line, which is completely mangled, and also the pieces of leftover
command pasted onto the ends of other commands nearer the bottom of
the list. The leftover command pieces aren't there to begin with, and
appear as the top continues to run - I suspect some kind of
uninitialised memory problem. I don't think it's just a display
update anomaly, as the pieces of extra text seem to move with the
commands.
My kernel is a home-grown 1.2.0 (compiled using GCC 2.5.8).

I think this is another symptom of sysvinit and other programs writing utmp
and wtmp incorrectly.

I don't think all if it can be, really. Why should bogus entries in
the utmp file (which doesn't contain process names) corrupt the
process name field in the top listing ?

You're right. I don't know what I was thinking of.

The infamous utmp/wtmp problem has gone away in R5 (or at least I
have not had it). I need to mark this bug done, along with about
a dozen or so more. :)
I think this is a problem with the general procps utilities, which
have not been updated in some time. `w' from this package was
displaying garbage (as Ian indicates that `top' is), so I replaced
it from the `w' from kmem-ps, modified to use the /proc file system.
I'll look into this.
