Selected Answer: ABC
To resolve this error and to prevent clients from receiving OOM command not allowed error messages, do some combination of the following: Set a TTL value for keys on your node. Update the parameter group to use a different maxmemory-policy parameter. Delete some existing keys manually to free up memory. Choose a larger node type.
