This error notice is one of the few SNACs that can be sent to the host and received by a client.
The SNAC can come from either origin source, this is because the message is basically forwarded from the source client, to the server, to the destination client.
This SNAC may only be sent as a programmatic response to an inter-client message. It is used to indicate that there was some problem with the original message received by the sender. If this SNAC is not immediately generated as a response, the client loses the right to send it at all and attempts to send it will be rejected by the server.
As transmitted, "cookie", "channel", and "username" are to be those which were presented in the inter-client message being rejected. As received, "username" has been changed to indicate the source of the error. It is not allowed to respond to a CLIENT_ERR SNAC with another CLIENT_ERR SNAC. Receiving a CLIENT_ERR SNAC does not grant the right to EVIL.

From Aleksandr Shutko: SNAC(04,0B) client message error or data SNAC(04,0B) ICBM__CLIENT_ERR
|
Client send this snac as reply to SNAC(04,07).
Server transfer it to client without changes, but only if its format is valid.
This snac also used for auto-messages (away message/busy message/chat message/etc).
First dword in msg-id cookies is actually the computer uptime in milliseconds
(ie GetTickCount(), at least this is what the ICQ Lite and the other official
clients I have tested uses).
