MAC address processing during tenant configuration can result in a "MAC exhausted" error even though there are available MAC addresses.
This can disrupt tenant configuration.
If the processing of a tenant's configuration releases MAC addresses to the partition's free list then this can erroneously cause a MAC exhaustion error. In this case there may be error logs in velos.log as well indicating failure to update or modify the MAC address pool.
Modifying the tenant in the CLI when adding VLANs to a tenant is less likely to run into this issue.
The code has been modified to log the error but not cause the misleading MAC exhaustion error and not block tenant configuration.
