Ah i see..

pawn Код:

new cstring[100];
    switch(reason)
    {
        case 0: format(cstring, sizeof(cstring), "(ID:%d ) %s has left the server... (Timeout)",playerid, pName);
        case 1: format(cstring, sizeof(cstring), "(ID:%d ) %s has left the server... (Leaving)",playerid, pName);
    }

    SendClientMessageToAll(COLOR_ALIEN, cstring);

You forgot "case 2", which is kicked/banned.
Because you forgot it, the "cstring" variable will be left blank and empty strings will make the server crash.
