The packet of the attack is "....getchallenge valve"

About 2000 Attack IP, sending 10 queries per second, deliberately low-speed queries, causing HLDS to be very lag and freeze, the version is the latest 8308.
I tried banning the IP segment, but it no effect, because the attacking IP changes dynamically.
Is there any way to deal with this new attack?

Broadband are very sufficient, but hlds process is directly frozen when the query attack comes,in the same time, the CPU share of HLDS process is very high.
The attack traffic is very small. An attack IP is only 1KB / s, but when 2000 Attack IP comes, HLDS will be stuck

Hope to get help fix, thank very much!
