Upon seeing this, my first though was that I have overlooked something
obvious; kern.maxfiles is indeed 3404 by default.

However, even one can increase it - e.g. to 4096 - this does not
change the behaviour with respect to the other:
...
# sysctl kern.maxfiles
kern.maxfiles = 4096
# sysctl proc.curproc.rlimit.descriptors
proc.curproc.rlimit.descriptors.soft = 1024
proc.curproc.rlimit.descriptors.hard = 3404
# sysctl -w proc.curproc.rlimit.descriptors.hard=4096
proc.curproc.rlimit.descriptors.hard: 3404 -> 4096
# sysctl -w proc.curproc.rlimit.descriptors.soft=4096
sysctl: proc.curproc.rlimit.descriptors.soft: Invalid argument
# sysctl -w proc.curproc.rlimit.descriptors.soft=3404
proc.curproc.rlimit.descriptors.soft: 1024 -> 3404
# sysctl proc.curproc.rlimit.descriptors
proc.curproc.rlimit.descriptors.soft = 1024
proc.curproc.rlimit.descriptors.hard = 3404
....

'jupyter-3.7 notebook-3.7' fails if I change the hardcoded value to
anything above 3404; it works with 3404.
