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

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.
