--- Comment #6 from Wolfram Schneider <wosch@FreeBSD.org> ---
The machine crashed again, with a kernel panic. Unfortunately, the kernel d=
ump
was not configured. I can access the kernel debug with a VNC web console, a=
nd
take some screenshots.

You can see the screenshots here:

you can see on the top procstat, sh and perl5.26.1 are in state "ufs"

and here is the perl process pid 28098 with sys_openat()
