Sorry for not > specifying earlier. I just tried doing (on 'next', since the new test is added there): make SANITIZE=address,undefined CFLAGS=-O0 cd t ./t0610-reftable-basics.sh --run=1-47 --stress and got lots of failures like you describe. But in my case bumping the timeout from 10s to 100s made that go away. So I think it was just the sanitizers making things _really_ slow and causing legit timeouts. Have you tried going beyond 2 minutes? That seems like a crazy amount of time, but I guess it's possible on a really overloaded system. Of course it's also quite possible that there are multiple issues and you are seeing something else entirely. :) -Peff
