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.
