Comment 3 Richard Purdie 2020-01-21 16:14:02 UTC 
I believe I spotted a pattern. This appears to only occur when a test is failing. I also wonder if there is a link to tests which "fork" since maintainers and reproducibility generate a lot of other processes.

Next steps may be to stress test with failing tests.
