Celery node fail, on pidbox already using on restart

I have Celery running with RabbitMQ broker. Today, I have a failure of a Celery node, it doesn't execute tasks and doesn't respond on service celeryd stop command. After few repeats, the node stopped, but on start I get this message:

[WARNING/MainProcess] celery@nodename ready.
[WARNING/MainProcess] /home/ubuntu/virtualenv/project_1/local/lib/python2.7/site-packages/kombu/pidbox.py:73: UserWarning: A node named u'nodename' is already using this process mailbox!

Maybe you forgot to shutdown the other node or did not do so properly?
Or if you meant to start multiple nodes on the same host please make sure
you give each node a unique node name!

  warnings.warn(W_PIDBOX_IN_USE % {'hostname': self.hostname})

Can anyone suggest how to unlock process mailbox?

Solution

  • Large log file or not enough free space was a reason, i think. After deletion all is ok
