We've seen a similar crash with the same error on CefSharpBrowserSubprocess.exe after several days of leaving a browser open using CEF 92.0.26.

Is the last reply regarding the CefCommandLineArgs removal confirmed to work?

Does the problem reproduce with version 96? Chromium site isolation is now enabled by default in CefSharp.

Edit: Our specific situation aside, does that change in CefSharp 96 address the crash?

It isn't clear currently, as this has only been observed on a single test system of ours so far.

We have CefSharp 96 (of whichever ends up being newest) slated to go into our next hotfix bundle in early '22.
We've ended up on 92 as a jumping off point prior to that, since we need to do a bit of extra work to distribute VC++ 2019 to customer systems.

So similar soaks will happen at some point with newer versions, but not yet. This was first observed in 89, so our first move was to get the test system updated to 92 before retrying the soak.

Update: We believe that the command line argument referenced in this thread has mitigated the process crash in CefSharp 92 in our case based on a 5 days soak we've just wrapped up.
Code: Select all
settings.CefCommandLineArgs.Remove("disable-site-isolation-trials");
