The only thing buying more RAM is likely to do is make the memory leak
behind this harder to reproduce.  Likewise increasing kernel tunables.

It may only be a short-term leak, i.e. something that would be recovered

Does FreeBSD have a kernel debug facility for this?  Is there a way to
look at a kernel dump file and identify by caller who allocated space?
