> In container-executor.c, delete_path() returns early when unlink() against a
> file or a symlink fails. We have seen many cases of the error being ENOENT,
> which can safely be ignored during delete.
> This is what we saw recently: An app mistakenly created a large number of
> files in the local directory and the deletion service failed to delete a
> significant portion of them due to this bug. Repeatedly hitting this on the
> same node led to exhaustion of inodes in one of the partitions.
> Beside ignoring ENOENT, delete_path() can simply skip the failed one and
> continue in some cases, rather than aborting and leaving files behind.
