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?
