I've noticed, that sometimes on some users it gives them this. How could I fix it and from where is comming?

Код:

[02:03:24] [join] David_Umbracato has joined the server (3:36.84.236.224)
[02:08:27] [warning] client exceeded 'messageslimit' 36.84.236.224:58029 (572) Limit: 500/sec
[02:08:37] [part] David_Umbracato has left the server (3:0)

Thanks in advance for your answers. This is a user from this night, wich I saw.

Info:
It doesn't give 'messageholelimit'
It gives 'messageslimit'
