Rhino keeps crashing whitout any save. A memory allocation failed and rhino will close

ENven after restarting, even turn off and on the computer, rhino wont work anay more. It let me do whatever I want, but as soon as I save, it crash giving me the erro in the picture.

On rhin its says that I have use 460MB and that there is still 13446MB free… so I dont undersand.

What could I do? It comes from RHino, not my computer as I have plenty of free memory.

Hi Cam,

This could indicate a hardware failure, where some of your RAM might be damaged.

A quick google provides many options to check this.

Here is a not so complicated way to test it:

Please report back what you find


Do you have any third-party plug-ins installed?
If so, you might try disabling them to see if the crashing stops.

Thank you very much @John_Brock and @Willem, sorry I couldn’t respond before. It is still crashing so I can not save any work, the only thing I can sve is the stl, but not .3dm files.

I checked and my computer is fine, thank you for the link. I think its Something about plug-in as it started this Strange behavior right after I accept to install a plug-in (as otherwise the first time when I clicked on no it did not download my stl. in rhino). I am still stuck, as I dont know any thing about plug in, which one it was etc.

@cam If you paste the result of the Rhino command _SystemInfo here we’ll be able to tell you.

Hi Cam - start Rhino and in Options > Plug-ins, filter the view for ‘Plug-ins that do not ship with Rhino’ .
Disable these (probably only one or two) and try saving - if it works, re-enable one or two plug-ins at a time and try again until, hopefully, at some point it will crash and you’ll have an idea which plug-in is responsible…


Thank you very much @nathanletwory and @pascal for your help!
When I use _SystemInfo command I obtain:

ALso when I check the plug-in in rhino as suggested, I have :

RhinoResurf is a plug-in which I neededseveral weeks ago, so it can not be this one.

Would you have any idea of which one I should delete (and how)? I was not able to find ‘‘Plug-ins that do not ship with Rhino’’…

Thank you very much for your help!!

Hi Cam - see Options > Plug-ins page

I would disable RhinoResurf and see if that makes a diffference.

Hi @pascal!
Thank you for your answer, for now its working, but it seems to me that it can not come from this as I did not had any problem with rhino when downloading and during the next few weeks. Also, suddenly after accepting downloading a plusg-in I had the almost Always since the error, but I dont know which plug-in it was.

In any case thank you very much for all your help!!
Wishing you a nice evening

In any case
