Hmm.. odd
(electron /)179># sysctl kern.maxfiles
kern.maxfiles = 10000
(electron /)180># limit descriptors 2047 ; limit descriptors
descriptors 2047
(electron /)181># limit descriptors 2048 ; limit descriptors
descriptors 2048
(electron /)182># limit descriptors 2049 ; limit descriptors
descriptors 2048
(electron /)183># limit descriptors 100 ; limit descriptors
descriptors 100
(electron /)184># limit descriptors 3000 ; limit descriptors
descriptors 2048
(electron /)185># sysctl -w kern.maxfiles=4000
kern.maxfiles: 10000 -> 4000
(electron /)186># limit descriptors 3000 ; limit descriptors
descriptors 2048
(electron /)187>#
