<p>
By default, the Redis configuration does not limit the
output buffer of normal clients (see
client-output-buffer-limit). Therefore, the output buffer
can grow unlimitedly over time. As a result, the service
is exhausted and the memory is unavailable.
</p>
<p>
When password authentication is enabled on the Redis
server, but no password is provided, the client can still
cause the output buffer to grow from "NOAUTH" responses
until the system will run out of memory.
