I am not sure how we can verify that. Did you mean accessing the task volume directory from `/files` endpoint again when the executor's work directory is gc'ed? But if the executor's work directory is gc'ed, certainly we will not be able to accessing the task volume directory from `/files` endpoint even it is not detached, failed to access task volume directory from `/files` endpoint does not mean it has been detached. - Qian ----------------------------------------------------------- This is an automatically generated e-mail.
