Getting “invalid feature key signature” while restarting aerospike after updating features.conf. Using Aerospike Enterprise Edition version 4.6.
If you speak to your Aerospike Primary Technical Contact he can add you as a Support Contact and you can raise the case directly or via the portal as you have an Enterprise contract.
The issue is most likely that the feature key has been modified in some way. I would suggest re-downloading and trying again.
