Running a large test suite gives error "ORA-04031 unable to allocate string bytes of shared memory" (4307901)

Code Tester 1.8 is able to run about 3500 test cases spread across about 50 test definitions with all in a single test suite.  After upgrading to Code Tester 2.5.1, running all the tests in the single test suite gave the following error:

“ORA-04031 unable to allocate string bytes of shared memory ("string","string","string","string")”

Running each Test Definition individually from the UI works fine.   Also exporting that single test suite with contains all the test cases results in “out of memory error.”
