一、您最好换一条内存看看，从错误信息来看是内存坏了。要不把内存的金手指擦擦再插上试试？\r\n二、最后的提示。您的主机名里没有域名，导致223错误。NIS服务没有开启，您的Name Service是用NIS提供的？NIS没有启动。\r\n如果对Sendmail没有需求，就停掉它。改/etc里的某某配置文件（除了更改/etc/services，好像还要把rc.d里的对应项改名，使sendmail不启动），然后pkill sendmail

呵呵 回复的及时啊 \r\n检查一下内存吗 系统panic 内存有报错的

KirovAirShip

要相信Solaris，你把内存检查一下。那种老内存还比较普及的Ultra-2,Ultra-250/450都是一样的。不知道你那个……

metor78

panic一般是内存原因，不排除软件导致

dogg

做一个最大化自检看一下吧

CPU0 Ecache SRAM Data Parity Error: AFSR 0x00000000.80400008 AFAR 0x000001fe.fc7c7710\r\n\r\n这个信息可能是CPU0坏了！！

jimjiaozhu

如果能把前面的一写messages也贴一下, 可能问题就不要怎么猜了.\r\n这个信息 应该是cpu的问题. 由于ultra10的cpu的ecache 是在cpu上的.

race

看着像是CPU，POST就知道了

谢谢大家指点，看起来8楼，9楼说的有道理\r\n另外请教race，你说的post是什么意思，怎么做呢？能不能给详细点啊？
