We have a server with a base of 50+ players and it's updated to 0.3z last week.
However we are DoSed by some bot attacker which I don't know.
CPU, RAM, DISK, and even NIC usage are just normal!
This is a kind of sa-mp server attack since all of the above resources are at least 75% free.
All I can share is that no-one of my recources usage change much before, durring and after attack.
The attack causes lag and server freeze during attack(all players are timed-out after 60secs ans server doesn't response even to queries in server browser!
I have tried to set maxnpc to number of my gamemode NPCs with no luck.. still attacker can do what he want.
So later I have managed to completly stop this kind of attack with setting maxnpc to 0 and removed all NPCs from gamemode.
Maybe a separate thread for processing NPCs help to mitigate this attack.
Is there a sulution to stop this kind of attack so I can get my NPCs back ?
