That will be the "is it already running" test in check_mailscanner not
quite working for your OS. Take a look at the script. You might want to
copy over the relevant Solaris chunk from check_mailscanner.solaris into it
(or just use the check_mailscanner.solaris script instead).

It's a thing that is almost impossible to do in a totally portable way.
