Manipulate batches of objects in mx 7

Hi, I'm moving our project from 6 to 7. When testing the microflows to proces large amount of objects, then out of memory errors show up.  We're using the default instructions to manipulate batches of objects, plus we added the endTransaction in the loop to fix the database load. This was working as expected in mx6, but after upgrade no more. How did you solve this in mx 7 or any updates on this?

Can you test with mendix 7.14 or 7.15?

The garbage collection behavior between 6 and 7 is the same (done at the end of a request), but we fixed a bug where too much state was returned to the browser. This can potentially lead memory issues. This was fixed in 7.14.
