-----------------------------------
Couple of things I noticed
1. I have seen this particular test manifest as a timeout issue a couple of
times. For ex:
{noformat}

2. All these failures also typically cause test_width_bucket to fail with weird
exceptions. So there seems to be a correlation there.
