I've run into this failure during make check in the past with

two consecutive make check runs fail with -j12 and -j8 on my 8

was the go test suite.  Has something changed recently that
could be behind it?  (My user process limit is 62863.)
What version of make are you using?  There was a bug where make could
lose track of children a while back.  Ask Patsy -- she may remember the
RHEL BZ and from that we can probably extract the version #s that were
affected and see if they match the version you're running.

I have make 4.0 and I'm running Fedora 23.  I haven't changed
anything on the machine in a while and used to be able to run
make -j16.  I still can bootstrap with that but make check
has been failing recently.  Three times yesterday (-12, -j8,
and -j12 again), but then the last one with -j12 completed.

The frustrating thing is that after the failure I have to
restart make check from scratch, and so it can waste hours.
I went back and found the bug we recently fixed in RHEL, but it was a make-3.8x issue.

Nothing useful in the RedHat/Fedora bug database.
