I've around 15k message a day and using push service. But since last week I've been attacked though Arrowchat. I'm not sure how they are doing it, but everytime i just rename the folder, the attack stops.
I've checked netstat and it's not a typical DDoS because there are not many ips, and the load of the server goes to almost 0. It's like some kind of slow flodding.
Does anyone experience something similar?
