Once the request is submitted the CPU% load on the server remains > 100% despite cancelling the request and terminating the session. The only way I have found to bring the %CPU back to "normal" is to re-start the JDV instance.

1. Created two files file1.csv (1M rows) and file2.csv (1M rows)
2. Created two source and view models and VDB
SQL statement is a carthesion product
3. Deploy VDB
4. select * from combinedcsv from SQL scrapbook on cancelLongRunningQueries VDB
5. Goto admin console
6. Go to the cancelLongRunningQueries VDB
7. Goto tab Requests and select Terminate
8. Goto tab Sessions and select Terminate JDBC session
9. CPU% load on JBoss java process remains > 100%
