This from LINT:

# The `maxusers' parameter controls the static sizing of a number of
# internal system tables by a formula defined in subr_param.c.  Setting
# maxusers to 0 will cause the system to auto-size based on physical
# memory.

It seems to work pretty well on any and every box I have ever built, so
unless your system has trouble determining the availalbe physical memory,
my guess is you can just leave it as is.  I am no kernel expert, mind,
but I don't think fiddling with this setting while trying to fix another
problem will help matters.
