Cause

The limit of heavy operators is reached on the backup (storage) node.

heavy_pool in the configuration of the PVA Agent on the node defines the allowed number of simultaneous heavy operations (backup creation/backup restoration/ve migration).

Resolution

Upgrade PVA Agent on the storage node to the version 6.0-2160 in which the default limit of heavy operations has been increased to 20 among other fixes and improvements.
