小.大咘XD
我去浪漫找到1篇文章關於卡CPU...
因為我看不懂所以給你看XD...- -"

解決辦法：
1、在源碼下 ItemSortHandler.java 這個文件 打開後內容如下.:


package net.sf.odinms.net.channel.handler;

import net.sf.odinms.client.MapleClient;
import net.sf.odinms.net.AbstractMaplePacketHandler;
import net.sf.odinms.client.MapleInventoryType;
import net.sf.odinms.client.MapleInventory;
import net.sf.odinms.server.MapleInventoryManipulator;
import net.sf.odinms.server.maps.FakeCharacter;
import net.sf.odinms.tools.MaplePacketCreator;
import net.sf.odinms.tools.data.input.SeekableLittleEndianAccessor;

public class ItemSortHandler extends AbstractMaplePacketHandler {

@Override
public void handlePacket(SeekableLittleEndianAccessor slea, MapleClient c) {
c.getPlayer().resetAfkTime();


slea.readInt();
byte mode = slea.readByte();

boolean sorted = false;
MapleInventoryType pInvType = MapleInventoryType.getByType(mode);
MapleInventory pInv = c.getPlayer().getInventory(pInvType);

while (!sorted) { //我懷疑是這裡導致死循環造成的服務器卡CPU的。。
byte freeSlot = pInv.getNextFreeSlot();
if (freeSlot != -1) {
byte itemSlot = -1;
for (byte i = (byte) (freeSlot + 1); i <= 100; i++) {
if (pInv.getItem(i) != null) {
itemSlot = i;
break;
}
}
if (itemSlot <= 100 && itemSlot > 0) {
MapleInventoryManipulator.move(c, pInvType, itemSlot, freeSlot);
} else {
sorted = true;
}
}
}
c.getSession().write(MaplePacketCreator.finishedSort(mode));
c.getSession().write(MaplePacketCreator.enableActions());
}
}
以上部分代碼是端裡原始的代碼。。個人分析因為上面的排列算法。 使用的 while (!sorted) WHILE循環導致當道具滿的時候，點排列按扭無法跳出循環而造成死循環,從而導致占用服務器CPU過大。。。。 下面是我修改的代碼。。大家可以複製整個，替換這個文件的內容..重新編譯即可....

package net.sf.odinms.net.channel.handler;

import net.sf.odinms.client.MapleClient;
import net.sf.odinms.net.AbstractMaplePacketHandler;
import net.sf.odinms.client.MapleInventoryType;
import net.sf.odinms.client.MapleInventory;
import net.sf.odinms.server.MapleInventoryManipulator;
import net.sf.odinms.server.maps.FakeCharacter;
import net.sf.odinms.tools.MaplePacketCreator;
import net.sf.odinms.tools.data.input.SeekableLittleEndianAccessor;

public class ItemSortHandler extends AbstractMaplePacketHandler {

@Override
public void handlePacket(SeekableLittleEndianAccessor slea, MapleClient c) {
c.getPlayer().resetAfkTime();


slea.readInt();
byte mode = slea.readByte();
byte s=0;
MapleInventoryType pInvType = MapleInventoryType.getByType(mode);
MapleInventory pInv = c.getPlayer().getInventory(pInvType);

for(s=0 ;s<90;s++){ //用這個替代while循環，從而解決死循環卡CPU問題
byte freeSlot = pInv.getNextFreeSlot();
if (freeSlot != -1) {
byte itemSlot = -1;
for (byte i = (byte) (freeSlot + 1); i <= 100; i++) {
if (pInv.getItem(i) != null) {
itemSlot = i;
break;
}
}
if (itemSlot <= 100 && itemSlot > 0) {
MapleInventoryManipulator.move(c, pInvType, itemSlot, freeSlot);
}else {
break;
}
}

} c.getSession().write(MaplePacketCreator.finishedSort(mode));
c.getSession().write(MaplePacketCreator.enableActions());
c.getSession().write(MaplePacketCreator.serverNotice(1, "重新排序完成!"));
}
