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. ----------------------------------------------------------------------- Acknowledgement sent to Ian Murdock : Extra info received and forwarded.

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).
