求教SUSE服务器宕机处理及故障原因分析的方法

wangfred1

公司一台SUSE的应用服务器，最近两次宕机，表现为能ping通，但是不能telnet、SSH连接。在服务器的显示屏打开后显示没有信号。这两次我都是直接断电重启处理的。但是在网上查了下资料，看到有说这样可能是SUSE假死的。想请教下这样应该如何恢复？还有原因如何分析？本人才开始接触，还希望能比较详细的说明，不胜感激！

我的cetos 5.4也出现过这样的问题，处理方式和楼上一样。我也想知道怎样来处理这种假死状态，望高手赐教，非常感谢。

上面是日志里到发现问题重启前的内容。跑的是OA应用的服务，resin服务器，数据库在另一台同样配置的机器上，没任何问题。
