@shanemcd Thanks for reporting this issue. I am able to reproduce the repetition of exec but not able to reproduce the Failed to create a temporary directory. In... error. Could you please let me know the container image used in this example? Problem might be container image specific.

@shanemcd Also, check if #204 solves exec repetition problem.
