Django Celery implementation - OSError : [Errno 38

问题:

I installed django-celery and I tried to start up the worker server but I get an OSError that a function isn't implemented. I'm running CentOS release 5.4 (Final) on a VPS:

    . broker -> amqp://guest@localhost:5672/
    . queues ->
        . celery -> exchange:celery (direct) binding:celery
    . concurrency -> 4
    . loader -> djcelery.loaders.DjangoLoader
    . logfile -> [stderr]@WARNING
    . events -> OFF
    . beat -> OFF

Am I just totally screwed or is there an easy way to resolve this?

回答1:

same issue on ubuntu 10, even after full rights on shmem are given - problem still here...

UP- finally done, /dev/shm was not mounted. so add shm to fstab mount shm set full 777 permissions on /dev/shm
