Error in v$sql.rows_processed. 1,000,000 rows per second

[emilton]

I am running oracle 9i on a Unix box ( 32 bit )
I have a small pl/sql procedure that uses a database link in the cursor and a commit command in the body. When I monitor the value of v$sql.rows_processed, that number increases about 1,000,000 rows per second until it reaches the maximum value for a pls_integer, 2,147,483,647 and then it becomes negative 2,147,483,647. The row count increases until it passes zero and then, +2,147,483,647. This cycle will continue based on the number of rows in the queried table (users).
I am looking for a reason this takes place and I have four concerns. What is the actual number of rows I am processing, I do not want a cartesian situation. Does this take place in 10G. Is there a work around. Should I be concerned about the accuracy of the v$ tables.
I posted an SR (TAR 5015075.993) with Oracle on Jan 3 but they have not offered any help.
Thanks, Eric
