OmniSharp Server crashed, garbled errors all around

Hi everyone,

It looks like there’s a problem with OmniSharp for me. After some time when I was working with a console project it just went nuts: it shows garbled errors everywhere in the code, though the code is okay. When I use Format Document function, it breaks all the formatting.

I can see there are some suspicious exceptions in the OmniSharp Log.

Here’s the file with the code where it misbehaves: https://gist.github.com/arsinclair/d4986d795034c83d2f72d10e2af87bde

The same code, but opened in Visual Studio renders just fine.

The root cause for the problem described in this issue was identified as change forwarding problem, and was addressed in https://github.com/OmniSharp/omnisharp-vscode/pull/4477.

I will close this issue now. If you encounter any issues with state sync between client and a server in the future, please open a new issue - thanks!

The same problem never stops occurring with me. It happens out of nowhere as well. No clear and common situation as well. It actually happens whenever: when getting intellisense, when syntax check is requested, when trying to get a definition, when trying to get a usage… The only way to have it working again is to fully restart VS Code.

The problem never occurred/occurs on small projects. But I don’t work on small projects. Something interesting: my associate is working with me on the very same big solution but… on windows; he does not face this issue, and his intellisense is much faster.

On a big project that takes 1mns for omnisharp to load, you can imagine that it is impossible to work, given the fact that the pb occurs after couple of requests to omnisharp. My developer life literally became hell.

I cannot publicly provide the solution here because it is too big and subject to a non disclosure agreement. As the solution is on azure devops, we can agree with an official developer of omnisharp to reproduce the pb on his environment

I noticed as well that the problem is more willing to happen when there are a lot of compilation problems in the solution (what happens when you rehandle a big chunk of code that has in impact in other projects of the solution).

I will update this ticket with detailed logs when the problem occurs again as at the moment, my code is stable again, so I face the problem much less.
