Under full performance load revoke toke returning below error:

{ "error": "Failed to find token with id :1cf7b79f-9268-4af9-836b-9731bc23b1d1", "error_description": "\nCTS: Query operation Failed:\nError: \nCTS: \nCTS: Error during partial query\nFilter: TokenFilter: Filter: [coreTokenId eq \"1cf7b79f-9268-4af9-836b-9731bc23b1d1\"] Attributes: " }

Also memory have been seen to be heavily utilised as RevokeToken calls start.
