ORA-00471: DBWR process terminated with error

Hello,
I had met a question. The oracle database will crash after about every five days. The "pmon" had detected the DBWR was terminated suddenly. I am very dismayed, because according to the other threads said, most of this issue was due to the Oracle Bug.

Is there any routines to figure out this error "ORA-000471"? Is this oracle bug, or system configuration fault?

The version of oralce is Release 10.1.0.2.0.

The version of platform is Linux 2.4.20, MontaVista(R) Linux(R) Carrier Grade Edition 3.1 .

I had try my best to resolve it and unfortunately did not achieve nothing.

You can refer the fllowing information. Your strong help and support is a great treasure to me for certain.
