It consumes 98% cpu, and can not be terminated with a ctrl-c when run interactively. This only occurs when using the AGG renderer; switching to GD prevents this behaviour. The attached (or maybe hyperlinked if it's too big) data set can be used to exhibit this problem: - Load the package hanging_ajax.mgp - In Studio, open the weblayout to !Library://ccgismap-ext/test/Layout/error_test - Preview this layout in the AJAX viewer (from the link in the layout editor) and use the mouse wheel to zoom in in increments until the server stops responding. - you may notice that at a particular scale, the feature no longer renders, though the server still responds. I saw this behaviour at about 1:100 on my 1280x1024 screen. This problem was initially found by Jonathan Manafi, and has been verified by Jason Birch, for MGOS 2.0 RC4." defect closed medium General 2.0.0 major fixed jmanafi
