Most likely explanation is that the test kill the DUT. Over to sheriffs to find owner of security.UserFilesLoggedIn.

Components: OS>Kernel
All this test does is log in and check some files on-disk. In this case, the DUT disappeared while the ui job was being restarted:

2018/12/04 19:48:57 Started test security.UserFilesLoggedIn
2018/12/04 19:48:57 [19:48:57.492] Restarting ui job
2018/12/04 19:52:27 Got global error mid-test: timed out after waiting 3m29.998s for next message

The messages file indicates that the DUT crashed abruptly (with bogus timestamps in the log?) and then rebooted:
