I have used Rhino for a while now and I have had a recurring problem over the past months, I cannot remember if it was always the case.
If I have a Rhino file open on my computer on the background, it will end up taking a huge amount of memory on my computer over time, even if it is a file as simple as a line drawing file that has almost nothing in it.
Translation in english: “your system used all the memory allocated to the applications.”, Rhino being at 187,37Go. (My computer has 32Go memory if I make no mistake)
I do not understand what causes this or what could fix it. If I quit and restart then it works fine again until I have to close and open again. Is there something about the fonctionning of the software that I am unaware of?
This is a small file that I made to see how precise I could get with line weight in PDF export. But does not seem to be linked to the size of the file I use.
Has this issue ever been reported ? I tried to look on forum but did not find.

Hello I am having the same issue with my MacBook Pro Here is the systemInfo:
I am running into the issue of it ramping up to 97 GB of Memory! I have no idea what to do. I reset all the files and settings on my computer and while that did help for general memory, it didn’t work for the application memory. Please help!

Is this behavior something that recently started happening?
Louis mentioned that this also happened in a small file with just a few lines. Is that also the case on your system? If so, how long does it take from launching Rhino to where large amounts of memory are taken?
Do you have a file open in Rhino and then let that sit in the background while working in a different application, and when you then get back this occurs or does that happen while you are actively working in the document?
Do you open and close specific panels a lot or do you tend to stick to a window layout which allows you to do most of what you need during a modeling session?
The more details you can provide, the greater become the chances for us to be able to find out what’s happening here.

This is recent with a file that does have a lot in it, about 500 MB. It tends to use a lot of memory when I try to render which makes sense but also happens when modeling. I’ve been trying to use only this file when modeling but typically will also have other applications like InDesign or Chrome open. It happens when I am actively using the file. I go between window layouts/views, often working in perspective view and sometimes a four window view.
When I am not doing anything and just having the file open it sits at about 32GB memory use.
