Re: [plexil-support] Memory issue

Catherine,

3.5 GB does sound excessive.  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.

Hello,
                We have a Main plan that will eventually have 32 plans with LibraryAction dependencies. 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?

Thanks,
Catherine
