We have found that the default setting
`image_cache_manager_interval=0` effectively *disables* the image
cache manager, but it still shows up as running in the logs. I've
reported this as a bug:

After setting image_cache_manager_interval to >0, the nova-compute
process took care of wiping the unused base files and now the nodes
are functional again.

Ciao,
Riccardo
