思科路由器不停提示：%SYS-2-CHUNKBADMAGIC 故障解决办法

路由器每间隔一段时间就提示：%SYS-2-CHUNKBADMAGIC : Bad magic number in chunk header,

上CISCO官网查询解决办法，官方给出的解决办法是：请联系你的当地技术支持。。。（纯粹扯蛋）。后来在一个老外的论坛上看见有人碰到过相同的问题，发帖如下：

Hi,
Does anyone know this is a bug ?

Cisco IOS Software, 7200 Software (C7200-IK9S-M), Version 12.3(14)T2

%SYS-2-CHUNKBADMAGIC: Bad magic number in chunk header, chunk 0 data 66AFCEE0 chunkmagic 6093EE60 chunk_freemagic 65B248F0-Process= "<interrupt level>", ipl= 4-Traceback= 0x607D29A0 0x60941AE0 0x6086C988 0x60190674 0x6019155C 0x60189700 0x609FF67C 0x6090EA14

碰到的问题跟我家的路由器出现的故障提示一样。。
结果有人回帖：
it's because of the fragmentation and VFR enabled on the router. Try the workaround. Disable VFR on all interfaces (no ip virtual-reassembly"), or just on these where the command "show ip virtual-reassembly" shows you reassembly count > 0

大概意思是：用show ip virtual-reassembly命令查看哪些端口开启了virtual-reassembly功能，并在接口模式中用no ip virtual-reassembly命令将其关闭
