• Game/AppID (with version if applicable): 10
• Current AMX Mod X version: 1.10 5467

# Problematic Code (or Steps to Reproduce)
#include <amxmodx>
#include <amxmisc>
#include <reapi>

public plugin_init()
{
        register_plugin("Query cvar", "1.0", "GH")
}

public client_putinserver(id)
{
        set_task_ex(10.0, "CheckCvars", id, .flags = SetTask_Once)
}

public CheckCvars(id)
{
        if(is_user_connected(id))
        {
                query_client_cvar(id, "cl_minmodels", "OnClMinModels_CallBack")
        }
}

public OnClMinModels_CallBack(id, const Cvar[], const Value[])
{
        if (equal(Cvar, "cl_minmodels"))
                if(str_to_num(Value) != 0)
                        rh_drop_client(id, fmt("Please use cl_minmodels 0"))
}

If use this query the server crashes in few minutes.

• The Hastebin content is gone.
• The "include" commands are missing the file names, maybe more is missing. Using code tags would avoid this issue. Mark the code and then click the Code icon '<>'.

Thanks for the answer, I edited my post so that everything works again, in terms of logs, the server just crashes, I have the .dmp file.
