Visual Studio OutOfMemory errors when saving files

ribkix 1

When I save a file in Visual Studio I get OutOfMemory errors. I literally have 32 GB of memory but ok. I tried to report the problem but the feedback page keeps saying that I don't have Visual Studio open. I have tried repairing Visual Studio already, updated and everything but it all doesn't help. I am experiencing this issue with WinForms C#.

It's for sure this isn't a RAM issue, but also not a CPU issue. My CPU is AMD Ryzen 7 3700X 8-Core so this shouldn't be occuring.

VS is limited to 4GB as it is a 32-bit process so having 32GB doesn't really help here. To help alleviate this newer updates to VS have started moving lots of stuff out of process to reduce memory constraints. However you can still run out of memory for large enough solutions.

I would recommend that you use the Report a Problem in the top right of VS to report the issue. As part of this you can replicate the issue while recording the problem and this will send the necessary information to MS for diagnostics.

You might also need to temporarily disable any extensions you are running to eliminate an issue with extensions. Extensions like ReSharper and CodeRush can use up a lot of memory, causing issues.

I also mentioned that I already tried doing that but the webpage keeps saying I don't have Visual Studio open while I do. I don't have any extensions on at all.

Are you running the latest update to VS? I've seen an issue a while back with a VS update that caused the feedback page to not work properly. I believe that issue has been resolved.

I don't believe we are going to be able diagnose this for you as it requires looking at the dumps of the process to see what is using up the memory. You could debug VS from another instance of VS to see where the memory is going.

I also mentioned that I updated Visual Studio already, and how exactly do I do "You could debug VS from another instance of VS to see where the memory is going."?

To debug in VS start your VS instance and set up the scenario. Then start another VS instance and use the Debug\Attach to Process to attach to the first VS instance. Then replicate the issue in the first instance. When it crashes you'll be thrown into the debugger and can try to debug the issue.

I got to Debug\Attach to Process but VS is not in the list.

I think I got an idea what's causing it. The form designer. I was using Blend in the mean while to see if that would help the issue, and now when I open a form it shows an error where I can continue and when I press continue I get a warning saying it costs lots of memory.

Glad to hear you might have identified the issue.

In regards to not seeing VS in the attach list the second instance should show the first VS instance. By default it should be auto determining what to use but if not then use the Attach To - Select button to specifically list both Managed and x86 processes as VS is both. Unless you're running as 2 different users you shouldn't need to check the Show processes from all users option. Search for devenv.exe which is the shell process that is running.

Hi @ribkix , you can try to open C:\Program Files (x86)\Microsoft Visual Studio\Installer\vs_installershell.exe, if the report problem page still doesn't work, please go to C:\ProgramData\Microsoft\VisualStudio\Packages, and confirm if the _Instances folder exists, if not, I'm afraid that you need to re-install visual studio.

the page is still not working and the _Instances folder is definitely there. I have reinstalled VS like 5 times and it didn't help anything at all.

I opened VS, opened a form and I couldn't even open it, it already said I don't have enough memory. I launched collect.exe and here are the logs: https://1drv.ms/u/s!Ak6gnbwF9NU1ajsWxSeuD9tyT2M?e=dKd5Jp

Hi @ribkix , thanks for sharing. From the logs, there are some components are incompatible with your current system. For example:

[42c8:000c][2021-04-06T18:39:26] Package Microsoft.Azure.PowerShell is not applicable: Required conditions are not satisfied: Not Powershell5 [42c8:000c][2021-04-06T18:39:26] Package Component.UnityEngine.x86 is not applicable: A 32-bit operating system is required, but you are running on a 64-bit operating system.

So, please try to update your system to latest version.

Dear customer, can you see the installed Visual Studio 2019 in your VS Installer window? Please try to run it as administrator from start menu.
Can you close the VS installer and click on “Tools” > “Get Tools and Features…” on the menu bar? Do you have any error messages? If possible, please share us some screenshots about the issue so that we can investigate it further.

I know what is happening. I am on a too high version. This is bad for the program, since even before updating this happened. I have never updated ever until this problem occurred, which means I had no choice than to run this version of Windows 10. Microsoft, this is your operating system and your software too, make sure to update your software to be compatible with the latest version before you release the new operating system version.
