Title:
Empty JSON caused: Error during
ComputeManager._run_image_cache_manager_pass: No JSON object could be
decoded
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
Hi.
An empty file CONF.instances_path/compute_nodes is causing the following
error. This prevents the image cache manager to run (i do not know if it has
some other consequences):

XXX.ifca.es:XXX.ifca.es
