Charles-François Natali <neolo...@free.fr> added the comment: """ OSError: [Errno 16] Device or resource busy: '/nfs/tmp/pymp-f7R9S6/.nfs00000000e039692f00000236' """
That's because the temporary directory is removed while a file inside is still open. And that's really likely the unix socket used by the server's listener. What happens if you do this instead: """ import multiprocessing manager = multiprocessing.Manager() manager.shutdown() del manager """ You should shutdown the manager before it gets garbage collected. > (the TMDIR directory is in a nfs server) Bad idea, for the following reasons: - you're actually lucky Linux allows binding unix sockets over NFS filesystems, some Unix flavors don't - you're likely to run into similar problems, because code which removes a temporary directory while having still an open FD is quite common, and will break with a tmp dir over NFS - mkstemp() and friends use O_EXCL to create a temporary file securely, and some NFS implementations of O_EXCL are unsafe (should be OK with NFSv3 and later though) - it's not a good idea performance wise ---------- nosy: +neologix _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13978> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
