It sounds like you have the NCM Export Configuration functionality enabled. Reference the "Select Settings for Device Configuration Export" section of the documentation located at https://techdocs.broadcom.com/us/en/ca-enterprise-software/it-operations-management/spectrum/10-4-3/managing-network/network-configuration-manager/network-configuration-manager-configurations.html
In the NCM Export Configuration subview in the Information tab of the Configuration Manager, the user sets an Export Directory.
So the issue is most likely one of the following:
- An invalid Export Directory specified
- The disk/partition is full or does not have any more space to create new files
- Permissions on the directory are preventing files from being created
