"top" is not part of the OS. This (possibly
old) one works on my system:

urt# /usr/local/bin/top -v
top: version 3.5beta12

urt# sizer -v
Compaq Tru64 UNIX V5.1B (Rev. 2650); Thu Dec 29 15:58:23 CST 2005

You might try downloading a recent version,
building it, and testing it, and then, if
that fails, reporting back (with more useful
information).

3.5.1 seems to be the latest released version,
with 3.6beta4 also available.

Top is not supported and can cause problems on the system. Instead of using TOP, use collect. Collect is a system monitoring tool that uses few resources and can run continuously logging the data to be viewed later.

Many useful programs are "not supported".

Plese describe these "problems". I don't use
it very much, but I never noticed any.

I don't know the problems because I never used that tool. But if you run a sys_check, there will be a recommendation of not to use that kind of tool. There should be a reason for that. Or maybe I'm outdated, anyway I prefer the use of supported tools.

You mean this?

Not knowing which version(s) of which
programs actually had a problem, I don't
find this advice very helpful. Also, I don't
run "top" "continuously", so I don't expect
any more trouble than I've already had, which
is to say, none.

Perhaps you are (or perhaps not). I prefer
to use tools which work, and which do what I
want done. "top" is one of these.

Let me know if you find a _real_ problem.
