AlliedModders - server crash (client-side commands)

Hello, I've been trying for about two days to understand what is causing server crash. After several attempts, I noticed that there is a player sending crazy commands via console and I guess that's the cause.

Code:

L 03/02/2019 - 12:44:38: Command: #!/usr/bin/python2, Args: 

L 03/02/2019 - 12:44:38: Command: #, Args: -*- Coding: utf-8 -*-" 

L 03/02/2019 - 12:44:38: Command: , Args: - Coding: utf-8 -*-" 

L 03/02/2019 - 12:44:38: Command: CloudZerg, Args: DDos - BotNet V i a Abuse 2016/

L 03/02/2019 - 12:44:38: Command: Denial, Args: Of Services Attack Starting..!!

L 03/02/2019 - 12:44:38: Command: Game, Args: Counter Strike DDos Attack Star

L 03/02/2019 - 12:44:38: Command: BotNet, Args: Damage is Very Strong and All R

L 03/02/2019 - 12:44:38: Command: Copyright, Args: 2018 (C) 2018 Services Service

Then server crash "Segmentation faul (core dumped) $HL_CMDt". Did someone know how can I avoid this?
