public OnPlayerDeath(playerid, killerid, reason)
{
    new string[128], pname2[24];
    GetPlayerName(playerid, pname2, 24);
    format(string, sizeof(string), "*** %s died.", pname2);
    SendClientMessageToAll(COLOR_RED, string);
    return 1;
}

And don't do a string of 256, its useless, max chat text is 128.
