[Maas-devel] Cluster download tasks completely block other jobs :(

Tue Jun 10 03:11:38 UTC 2014

I just installed a test package on my test rig to play with my new DHCP
code, and noticed that after starting a node up, there was no job
appearing in the log.

On closer inspection, it appears that there are many download tasks
running which were kicked off, I think, by the regular auto-import:

[2014-06-10 12:48:50,631: INFO/MainProcess] Received task:
provisioningserver.tasks.import_boot_images[6590b4bd-5498-46b5-ad4d-69d21e096dd4]

So now, all the celery threads are busy downloading boot resources, and
none are available to start nodes, for example.

I've filed a critical bug about this.
