The file gets created during the check when you call sink('NUL'):
https://github.com/cran/parfm/blob/8c3f45291514aedde67cecf0b090ddd3487f3ada/R/parfm.R#L260-L299
It mostly works on Windows, where "nul" with any extension in any
directory is the null file, but it creates a file named 'NUL' on other
operating systems. It also breaks the non-default sink, if any was set
up by the user.
Does optimx::optimx produce output that can't be turned off otherwise?
(Does it help to set control$trace = 0?) Have you tried
suppressMessages() or capture.output() with nullfile()?
