pytest: FileExistsError: [Errno 17] File exists: '/tmp/pytest-of-jenkins/pytest-0/.lock'

Hi there -

Just need to know what’s happening on this one, this seems to be new code in py.test in version 3.9.1, my other build server running 3.8.2 doesn’t have this issue.

is there…some kind of revolving numeric scheme such that more than one runner (I’m using pytest-xdist, 1.23.2 on both environments) is conflicting on this?

this is SQLAlchemy’s test suite running on jenkins.

stack trace:
