刚学solaris，请教系统日志的内容是什么意思？

将薪比薪

操作系统：solaris 10
请问：1、Jan  5 05:17:42 HAZZ-EOMS-DB1 lw8: [ID 722029 kern.notice] Main, up 360 days 12:28:41, Memory 7,414,360
             这代表什么意思？
      2、Jan  7 10:55:03 HAZZ-EOMS-DB1 rootnex: [ID 349649 kern.info] ramdisk0 at root
Jan  7 10:55:03 HAZZ-EOMS-DB1 genunix: [ID 936769 kern.info] ramdisk0 is /ramdisk-root
       这代表什么意思？

    谢谢解答！！！

启动了多久

内存多大

rigofree

应该是e2900的系统bug， 需要Firmware升级补丁114526-01

将薪比薪

内存：
prtconf后：Memory size: 32768 Megabytes
启动时间：
   这是个数据库服务器，很少出问题，好像一直在使用。。

将薪比薪

服务器bug？请问你从哪看出来的？
