Hi,

Database crashed with the Below error

Tue Jun 15 23:01:05 2008
USER: terminating instance due to error 472
Instance terminated by USER, pid = 23881
Wed Jun 16 00:17:47 2008

The instance gets crashed mostly every week and the alert log shows
----------------------------------------------------
Fri May 9 23:01:05 2008
USER: terminating instance due to error 472
Instance terminated by USER, pid = 29028

Mon Jun 2 23:01:04 2008
USER: terminating instance due to error 472
Instance terminated by USER, pid = 1400

Tue Jun 10 23:01:05 2008
USER: terminating instance due to error 472
Instance terminated by USER, pid = 23881
----------------------------------------------------

Also it's very interesting that the time is identical on the instance
failures (23:01 )

i have also checked OS logs. But i could not find any relative
information related to the instance crashed on that particular time.

Kindly advice if  any one come across this issue

Thanks,
