We believe we have significantly improved memory management in the development version, but there may be issues building it in some environments. -- Chuck On Mar 13, 2014, at 8:40 AM, Catherine Szeto <Cat...@ti...<mailto:Cat...@ti...>> wrote: There are 93264 lines total in all 71 plx files.

The total number of nodes for all 72 plx files is 3249. I'm working on getting the total number of lines for the plx files, but for a ballpark, the average plx has about 3000 lines, with a handful of small ones at around 500 lines. The memory size increases monotonically as Main.ple is trying to load. This takes about 2 min to load, and about 6 min before the giant while loop in Main.ple iterates quickly. Once Main.ple is up and running, the memory usage stays about the same. Catherine From: Dalal, Michael (ARC-TI)[Stinger Ghaffarian Technologies Inc.

Some questions… Can you provide some quantitative information about the plans: total number of nodes (<Node> elements in the .plx files), total number of lines of the .plx files? Can you characterize the memory usage? Does plexilexec occupy 3.5 GB upon loading the Main plan (which effectively loads all the library plans)? Or after running for a while? Does memory size increase monotonically? No suggestions offhand for reducing the memory footprint, but I'll talk about this with others, and the information above will help. I don't think the Plexil Viewer or the related startup options are an issue.

We tried running the plan through the plexilexec with 25 of these dependent plans integrated. The plexilexec is using about 3.5 GB of memory, which seems excessive. We have several more plans to go that will be fairly large, so this is going to be a growing problem. Is there anything we can do to better manage the memory being used by the plexilexec to make the memory use more reasonable?
