I first try it by changing /boot/loader.conf[.local]. Only to check if
100000 is invalid I changed /boot/defaults/loader.conf

kern.maxproc is set at boot time, it is not writable in multiuser mode.

I don't think this results from the jails. At boot time there is no active
jail. And kern.maxproc sets the size of the process table which is global
for the host including all jails, I think.
