This is probably one of those spoofed ip attacks + acks raknet layer attack. Have you tried this plugin to prevent spoofed connections?:

You can also set ackslimit to lower value in order to reduce cpu usage during attack.

I know. This plugin not only protects against "server full" attack, but also protect you from spoofed clients. Your server didn't respond, because it was probably attacked with many different ip addressess and their target was raknet acks system wich is vulnerable enough to freeze/hang server for a while, that's why your server doesn't crashed and all players timed out.

There is: 0.3.7 version of sa-mp has this kind of protection or better one, but it's not released yet.

We already have the same problem on 0.3.7-RC1 , got the message, the server gets shutting down. I wrote a new topic about it.
