With the release, I have some Memory tables that fill only with a single record rather than the small number expected. All these tables use an SQL query similar to your code. My first guess was that the memory driver needed to be updated but this seems to hold another possibility.
Wondering how to test?
Thought this might do the trick and solve my GPF and limited records retrieved problems with v13505,
Unfortunately, that seems not to be the case so far. Oh well, would not be an enjoyable task to uncheck OPT for 200+ tables either.
