Comment 3 for bug 1387133

From the database log:

2014-10-29 04:25:23 CDT LOG: checkpoints are occurring too frequently (4 seconds apart)
2014-10-29 04:25:23 CDT HINT: Consider increasing the configuration parameter "checkpoint_segments".

2014-10-29 04:25:25 CDT HINT: Consider increasing the configuration parameter "checkpoint_segments".

And then:

2014-10-29 04:45:03 CDT ERROR: duplicate key value violates unique constraint "maasserver_componenterror_component_key"
2014-10-29 04:45:03 CDT DETAIL: Key (component)=(maas-import-pxe-files script) already exists.

Nodes will not be able to provision without boot images. Visit the boot images page to start the import.') RETURNING "maasserver_componenterror"."id"

(and then the same every 5 minutes after that)
