We have a new version of our app that we published out which utilizes CefSharp to serve up web pages for the user (the old version used the build-in .NET browser control).
Since upgrading, a handful of users have experienced random crashes that list the faulting module as C:\WINDOWS\system32\wbem\fastprox.dll. They don't seem to be taking any particular actions when this occurs (in fact, some of them just have the program sitting idle) and it doesn't happen for every (or even most) users.
Unfortunately, the error details don't include any useful information except the faulting module (this comes from Event Viewer), and info on what exactly fastprox.dll does is scarce online. I've spent several hours combing through Google trying to find something to point me in the right direction - but nothing has helped so far.
At the moment, I'm not even sure where to start troubleshooting this, since we can't replicate it reliably. Any info on fastprox.dll or how it interacts with CefSharp would be greatly appreciated, as would any suggestions on troubleshooting this issue.
