BTW, 4.6 is fairly old. Please try to update to 4.10 or later.

If you want to see what the current value is, do "sysctl kern.maxfiles". How
large you can increase it is a complex question, it depends on what other
options are configured and how much kernel memory is being reserved, but you
can make this much bigger if you need to.
Anyway, it might be a good idea to run fstat and see what is using all of your
file descriptors; maybe tuning that would be better than tuning the system...
