sysctl kern.openfiles will tell you how many files are open. sysctl kern.maxfiles will tell you the current system maximum. On recent FreeBSD revisions, you can live modify kern.maxfiles doing: sysctl kern.maxfiles=100000 (For example) You probably want to increase your maxusers, either by recompiling the kernel with a higher limit, or by dropping: kern.maxusers=256 (or a related big number) into /boot/loader.conf.
