One of the nightly-qa-systemd runs on the AB [1] failed and apparently the qemu image took longer that the defined timeout time, so at some point the AB kicked out the build. To avoid build folder removal, the folder was moved to [2] on the proper slave machine [1] https://autobuilder.yoctoproject.org/main/builders/nightly-qa-systemd/builds/523 [2] /home/pokybuild/yocto-autobuilder/yocto-worker/nightly-qa-systemd-archive/build/build/tmp/work/qemux86_64-poky-linux/core-image-sato/1.0-r0/testimage
This problem most probably happened due to a high system load. With the introduced commit [1] which IO tasks can be prioritized, it fixed the problem indirectly. In case the problem presents in the future, it should be analyzed further. [1] http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=290534d3ff53b3c0a50e480863474d1785088c5a
nothing to investigate; timeout will not be increased.
