Issue descriptionBrowsing through logs, I'm seeing that DUTs in the Autotest Lab accumulate a lot of crash dumps with the name "debugd" embedded in them. To see it, I'm running commands like this: $ dut-status -f -b elm -p bvt -d 8 | grep provision | sed 's=.*\(results/.*\)=gsutil cat gs://chromeos-autotest-\1*/status.log=' | sh | grep crashdump That produces lots of lines like this: INFO ---- ---- timestamp=1528208125 localtime=Jun 05 07:15:25 Host crashdump exists: /var/spool/crash/debugd.20180605.071352.2165.meta The problem is widespread, but not universal. I've seen "debugd" dumps on caroline, peach_pit, and kevin, but not nyan_big or elm.

+lhchavez to confirm: The crash is likely caused by https://chromium-review.googlesource.com/c/chromiumos/platform2/+/1053426 and fixed by https://chromium-review.googlesource.com/c/chromiumos/platform2/+/1086028

The problem stopped with the canary that included crosreview.com/1086028 $ dut-status -f -b peach_pit -p bvt -d 8 -u '2018-06-05 11:00:00' | grep provision | sed 's=.*\(results/.*\)=gsutil cat gs://chromeos-autotest-\1*/status.log=' | sh | grep debugd | wc -l 1632 $ dut-status -f -b peach_pit -p bvt -d 8 -u '2018-06-05 19:00:00' | grep provision | sed 's=.*\(results/.*\)=gsutil cat gs://chromeos-autotest-\1*/status.log=' | sh | grep debugd | wc -l 0 |
