Help! `ps' is going flakey on me!

[Lord Frith]

`ps' is giving me messages like "no room in text table" and "ps: error
reading ecmx from /dev/kmem"  and "error reading namelist." In single
user mode it simply prints the banner for `ps' like so...

"PID TT STAT  TIME COMMAND"

but no shows me no processes!

Does this sound like a familiar problem?  I did add some new disks and
recompile vmunix to use those disks but other than that I can't see what
the problem would be.  Vmunix is intact in the root.
