Thanks for the information.

So you have 16G of RAM which should be plenty for an 8-job
build.

I did a bit of looking around and this (the 'can not execute
clang++: too many open files' error) appears to be related
to the limit on the number of open files in Mac OS. There
appears to be both the per-process (ulimit -n) and the
per-system (sysctl kern.maxfiles) limits. I don't think this
is the per-process one since I would have expected it to
also fail with -j1. So it's probably the global limit. Was
the machine otherwise loaded with other tasks when you got
this error?

Ok, that's interesting, we will look into this.
