I bet there is some = bad code in the Webdna engine itself ... that does not do "garbage = collection" properly... does not re-free up RAM that was used, under = certain conditions ... and when our scripts get near the hardware RAM = limit, then this weakness, in the heart of Webdna, gets uncovered.
