aix系统连续两天自动产生dump

服务器型号： IBM，9133-55A
应用情况：oracle+weblogic服务器器，没有HACMP
补丁情况：
instfix -i |grep ML:
ALL filesets for 5.3.0.0_aix were found.
ALL filesets for 5300_01__aix were found.
ALL filesets for 5300_02__aix were found.
ALL filesets for 5300_03__aix were found.
ALL filesets for 5300_04__aix were found.
oslevel -s : 5300-04-00

此服务器连续几天出现如下信息：
IDENTIFIER TIMESTAMP  T C RESOURCE_NAME  DESCRIPTION
A6DF45AA   1221095711 I O RMCdaemon      The daemon is started.
EC0BCCD4   1221095611 T H ent1           ETHERNET DOWN

目前已经排除是oracle的问题，查看以前帖子好像是系统的核心错误，除了重新安装系统还有解决方法吗 ？

先dump系统还是能自动起来 ~~~
