问题虽然在交换机重启后解决了，但是不明白问题原因，我用超级终端访问，显示的信息如下：<br />-Process= "L3MD_STAT", ipl= 0, pid= 32<br />-Traceback= 1B9F24 1BBEEC 1BC8E4 1CA444 1CA4F0 2D2FA4 2D4CB0 2D4D94 68CF2C 68D480 1DB024<br />24w0d: %SYS-2-MALLOCFAIL: Memory allocation of 140 bytes failed from 0x1BC8E0, alignment 0 <br />Pool: Processor Free: 3761892 Cause: Memory fragmentation <br />Alternate Pool: None Free: 0 Cause: No Alternate pool <br />（给某一个进程分配内存的时候出错，可用内存池为0）<br />-Process= "L3MD_STAT", ipl= 0, pid= 32<br />-Traceback= 1B9F24 1BBEEC 1BC8E4 1CA444 1CA4F0 2D2FA4 2D4CB0 2D4D94 68CF2C 68D480 1DB024<br />%% Low on memory; try again later<br /><br />Local Memory Statistics <br />Free = 3761892 Total = 54195772 Used = 50433880 <br /><br />%% Low on memory; try again later<br />......<br />其他的基本一样，有哪位高手能帮偶解读一下，是什么原因造成内存不足？先谢谢了 <img src='style_emoticons/default/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' /> <br /><br />是不是受到了内存溢出攻击？ <img src='style_emoticons/default/sad.gif' border='0' style='vertical-align:middle' alt='sad.gif' />

什么软件版本,能不能在出现故障的时候报tech信息抓下<br />从信息中可以看到提示原因是内存碎片,可以试着抓取下以下信息<br />show memory allocating-process totals <br />show memory summary <br />show logging

show memory allocating-process totals <br /> Head Total(<img src='style_emoticons/default/cool.gif' border='0' style='vertical-align:middle' alt='cool.gif' /> Used(<img src='style_emoticons/default/cool.gif' border='0' style='vertical-align:middle' alt='cool.gif' /> Free(<img src='style_emoticons/default/cool.gif' border='0' style='vertical-align:middle' alt='cool.gif' /> Lowest(<img src='style_emoticons/default/cool.gif' border='0' style='vertical-align:middle' alt='cool.gif' /> Largest(<img src='style_emoticons/default/cool.gif' border='0' style='vertical-align:middle' alt='cool.gif' /><br />Processor C4E1C4 54195772 4951452 49244320 49083492 49096624<br /> I/O 80000000 8388608 1209520 7179088 7132408 7131592<br /><br />Allocator PC Summary for: Processor<br />..太长了，这个要么？

有没有试过将一部分端口shut down看看

<img src='style_emoticons/default/ohmy.gif' border='0' style='vertical-align:middle' alt='ohmy.gif' /> 这是正常时的信息吗?

排除病毒原因了吗?

2004-12-8 16:32 zn8903

暂时挂个sniffer看下先

2004-12-8 16:32 快乐小猪

第一楼的信息是故障的时候抓下来的，因为无法登陆，只有这么多

<img src='style_emoticons/default/glare.gif' border='0' style='vertical-align:middle' alt='glare.gif' /> 不是我想要的结果,还不敢确定<br />Other symptoms of this type of buffer leak are "%SYS-2-MALLOCFAIL" error messages for the pool processor<br />Buffer leaks are Cisco IOS software bugs.<br />o fix known buffer leak bugs, you may try upgrading to the latest version in your release train
