You can monitor module load/unload activity (especially autoload!)
by setting sysctl kern.module.verbose=1 and watch for activity in
/var/log/messages

I've seen "unexpected" module load/unload activity before, when
something was trying to execute an unknown compat/emulation.  All
of the possible compat modules get autoloaded, and then they get
autounloaded after 10 seconds.  And cycle repeats.

(I forget what the specific trigger was, but I think it was some
strange shebang thing in a shell script.)
