"Not enough quota is available to process this command" exception when calling Document.CloseAndDiscard or AcadApplication.Documents.Open

I am a developer for an ACA plugin and recently I've been experiencing an infrequent issue with using Document.CloseAndDiscard and AcadApplication.Documents.Open where I sometimes get this error:

If I try to continue past this popup AutoCAD Architecture crashes.

The code that I am running is like this

void CloseDrawing() { Document activeDoc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument; activeDoc.CloseAndDiscard(); // sometimes crashes here } void OpenDrawing(string fullFileName) { AcadApplication acadApp = (AcadApplication)Application.AcadApplication; Autodesk.AutoCAD.Interop.IAcadDocument baseDwg; baseDwg = acadApp.Documents.Open(fullFileName, true, null); // sometimes crashes here baseDwg.Activate(); }

This problem is something that I have only been able to reproduce in AutoCAD Architecture 2022, but since I can't consistently reproduce this I cannot confidently say that the issue exists only in 2022 and not previous versions as well.

Has anyone experienced this issue before, or have any idea what could cause this? My code base is so large that I have no idea where to begin looking for what could be contributing to this error since the exception is originating from an AutoCAD method.

Below is the call stack and last unhandled exception from dumpuserinfo.xml

This is a duplicate of a post I made on the AutoCAD Architecture Forum since that was the wrong forum to ask my question. My original post can be found here: https://forums.autodesk.com/t5/autocad-architecture-forum/quot-not-enough-quota-is-available-to-process-this-command-quot/td-p/12367258

I hope that if you have these 2 methods (CloseDrawing()/OpenDrawing()) used as generally shared code, you have remembered very well that they are ONLY used when your code in the AutoCAD plugin runs in APPLICATION CONTEXT, not in DOCUMENT CONTEXT.

Since you did not show or mention how these 2 methods are called, I am not sure if the AutoCAD error/crash is due to the methods being called in document context: if you do, they would crash AutoCAD for sure. So you have to look into it. OTH, if you do understand Application context and Document context well and calls the 2 methods only in Application context, the error would be a bit of mystical: I never saw something like this (mentioned "enough quota..."). Again, showing more relevant code where these 2 methods are called might be helpful.
