Too many attributes

This error means that the client is sending too much information in a packet. It is due either to a misconfigured client or a possible attack on the server. Either way, you should check what the client is sending via tcpdump or wireshark, before changing the server configuration.

The default value for max_attributes is high enough for most common use cases. However, if you do increase this limit, be careful. It might make the server vulnerable to resource exhaustion attacks.

Each listen section has a max_attributes setting to limit the number of attributes that can be included in a single request. By enforcing this limit, the server protects itself from clients that might try to overload it.
