Public bug reported: We have most reliably reproduced this on a Standard_B1s in Azure in the North Europe region (>80% of the time). Tests in other regions/VM types do not show this failure as often (<1%). We have reproduced this in Xenial, Bionic, Focal, and Groovy. We saw an increase of test failures around a month ago.
