The crash isn't normal, file a bug.

There are some ways to do what you want.

First: you could refuse anonymous calls (but it might be a no-no in your
job.)

Faster: forbid (drop, not reject) the whole IP adresses range that bothers
you to at the firewall level (113.96.0.0 - 113.111.255.255)

Other: may be there's another possibility into FS but the former is still
faster as it instantly refuse the connexion instead sending it to FS thus 
eating CPU to do that.

Last: Crack defense computers and nuke China.
