Public bug reported: With the default MAAS install I was having a problem where celery would become unresponsive and stop running new tasks (including powering compute nodes on/off) after a while, and eventually the system would have out of memory errors. The problem seems to have been that the queue was filling up with dhcp_upload_leases tasks (I checked on this by getting tasks out with the amqp tools...). This problem goes away if the timedelta in /usr/share/maas/celeryconfig_cluster.py is changed from 1 minute to 5 minutes.
