I've seen at least two occurrences of a non-deterministic test failurein qemu for x86_64 on hydra. Both are essentially the same, except forthe random seed. Here's the relevant log tail of the most recent one:
Toggle snippet (14 lines)GTESTER check-qtest-armsocket_accept failed: Resource temporarily unavailable**ERROR:tests/libqtest.c:192:qtest_init: assertion failed: (s->fd >= 0 && s->qmp_fd >= 0)GTester: last random seed: R02S68ad7b4ad35e64a4283ad867738ae469/tmp/nix-build-qemu-2.3.0.drv-0/qemu-2.3.0/tests/Makefile:416: recipe for target 'check-qtest-aarch64' failedmake: *** [check-qtest-aarch64] Error 1make: *** Waiting for unfinished jobs....phase `check' failed after 117 secondsbuilder for `/gnu/store/fv3kfpi3j7vg692ibkfaw6rvid1yabvj-qemu-2.3.0.drv' failed with exit code 1@ build-failed /gnu/store/fv3kfpi3j7vg692ibkfaw6rvid1yabvj-qemu-2.3.0.drv - 1 builder for `/gnu/store/fv3kfpi3j7vg692ibkfaw6rvid1yabvj-qemu-2.3.0.drv' failed with exit code 1guix build: error: build failed: build of `/gnu/store/fv3kfpi3j7vg692ibkfaw6rvid1yabvj-qemu-2.3.0.drv' failed
The excerpt above was from the first attempt of the following build:
http://hydra.gnu.org/build/557468
After restarting the build, the second attempt succeeded.
I saved a full log from another similar failure on 10 June 2015, but Ineglected to save the other details. Here's the relevant tail:
