Hi, I have a problem with 11gR1(

The application is only runnig one query every 5 seconds and other query every 3 seconds. There are not other activity with the application over the database.
There is only one user in the application and the CPU consumption starts to rise up to 100%.

The execution time for each query is 30ms. Furthermore, this problem only occurs in 11gR1. In 10g database ( or is not happening. We have running the same application since 4 years and this never happened.

We update the statistics every day.

Anyone have any idea?
It happened something like this to someone?

Thanks in advance,
