There is no easy way to tell because the problem results in a large
variety of reported bugs. The best thing to do is to get the thing
upgraded to the latest -stable and see if the problem stops.
Alternatively, if you still have the original 4.4.0 source tree, you
can adjust UPAGES from 2 to 3 in /usr/src/sys/i386/include/param.h
and recompile / reinstall just your kernel. This takes much less
effort.
I don't want to get hopes up too high, this might not be the problem.
But then again it could...
