System crash caused by memory leak

Hi MikeT ,
thank you very much for this feedback and the explanation.

I confirm with the latest nightly build the Page Fault count is a lot more under control.
There still is some after some time and usage but clearly it is much much better.

Also, 1P desktop use much less CPU cycles (even at rest) than before (it was quite noticeable with the last version).
In my opinion, the loop was the culprit in both cases.

So, a great improvement!
Thanks a lot!

Hi folks,

The page fault issue should now be greatly improved with the latest nightly build, 1Password for Windows 8.10.9 (81009021).

@aro148, I've asked for more details that we can share. My basic understanding is that it was due to how we were setting memory protection on our processes, which has its own challenges on specific Windows versions as well as domain/user types. It was stuck in a loop on business/enterprise versions after we were updating our internal Windows libraries in the last update.

Hi,
I am seeing that in Windows 10 Pro also

As a developer, I would appreciate it if you could share the cause of the high Page Fault Count associated with Win11 Enterprise.

Hi @aro148,

Just confirmed it is continuously increasing in PF count on the W11 enterprise side.

I'll file an issue and we'll get that fixed.

ref: dev/core/core#22700

I have checked the second system, a 5800x AM4 with 32 GB with Win11 Home, same Patch Level. It does not have the issue.
Here is another screenshot of the process with the issue:

If I suspend or kill the thread 26596 with the start Address "index.node!git_patch_owner" the issue will go away. At the first look, 1Password seems to run properly.
There is an open support call with ID #YYF-91118-712. I send everything via mail.

Thanks for listing your specs.
I'll take a look on how it reacts on Windows enterprise version and get back to you. Some of the recent regressions were only found on the Enterprise version.

Hi, it is production branch and nightly branch. This issue happens immediatelly after starting 1Password.
My System is:
7950x3d AM5, 64 Gb, Windows 11 22h2 Enterprise with 06-2023 Update and latest available drivers and bios. I am using desktop app, and browser plugin for Edge,Chrome,Brave and Firefox.
As I can see, you obviously don't have this issue on your system. I will check my second Windows 11 PC to see if this one behaves the same way.

Hi @aro148,

Thanks for reporting that. Can you confirm which build of 1Password are you using?

How long has 1Password been running when you took that screenshot?

Here, this was the number with 1Password running since yesterday.

Installing the latest nightly build from last night and a new start:

Maybe it has something to to with it. 1Password process has the highest pagefault counter all the time.
