>-Release all- may not work in the middle of the app running, otherwise I will purge all app objects from memory. right?

That is correct. I was merely pointing out that if you do a CREATE FORM/RELEASE FORM wrapped in SYS(1016)s, you may not necessarily be proving anything. You might have to write some logging code to narrow down the problem. You might also use SYS(1011) (memory handles) as a diagnostic tool as well.
