Problems with linprocfs(5) and htop

[Florian Unglaub]

I compiled sysutils/htop from the ports collection and noticed that it
does not display any process information as it's supposed to do. Instead
I get a blank screen (see [0]).

htop relies on linprocfs(5) to gather process statistic. linprocfs is
mounted:

linprocfs on /usr/compat/linux/proc (linprocfs, local)

There's also a thread on the FreeBSD forums [1], but no solution to the
issue so far. 

Similar issues appear when using utop [2]. This looks like a general
linux-emulation/linprocfs issue to me. Does anyone have any ideas what
might cause those issues or how to resolve them?

Regards
Florian.
