Have you managed to recreate the memory leak using the PARSE inside a loop or was that an educated assumption?

I'm not a service engineer, I'm a developer. It takes something fairly seismic to make me actually try things out - so you can safely assume that it's the latter.

Any plans to address this issue in the future?

Well, strictly speaking this is a documented behaviour, not a defect, not a memory leak. If you create 10,000 parsers in a loop within a flow, the flow will not deallocate those parsers until the end of the flow ( just in case you might have wanted to reuse them ). So it ends up looking very much like a leak, but in fact all the memory will eventually be reclaimed ( assuming that the EG is still around to reclaim it ).

Thanks for your help Kimbert. I think I have my head around this behavior now. Al
