Run a build with a lot of jobs in parallel, and it's not hard to hit
the process and file descriptor limit.  I started seeing this a few
years ago when I began using a 24-core machine for pkgsrc builds.
Maybe there are also some things that leak file descriptors, but the
maximum number of processes and descriptors should really be scaled by
available RAM by default.
