[bobombolo]

actually the first time i opened a file it worked, after that it was broken.

[bobombolo]

i also tried changing the settings.json "dotnetAcquisitionExtension.existingDotnetPath" to /usr/share/dotnet or /usr/lib/dotnet/dotnet to no avail

[dibarbet]

@bobombolo two requests -

1. can you set the dotnet.server.trace configuration to Trace and post the contents of the C# log here?
2. It looks like the process is still active and failing to shutdown, so a process dump here would be useful. The instructions to collect a dump via dotnet-dump are here - https://github.com/dotnet/diagnostics/blob/main/documentation/dotnet-dump-instructions.md#installing-dotnet-dump . Generally it would be dotnet-dump collect --process-id <PID of Microsoft.CodeAnalysis.LanguageServer here> after you install the tool. Can either upload here (if its small enough), or email me (listed in my github profile).

[bobombolo]

owner@navi:~$ dotnet-dump Required command was not provided.

Usage: dotnet-dump [options] [command]

Options: --version Show version information -?, -h, --help Show help and usage information

Commands: collect Capture dumps from a process analyze Starts an interactive shell with debugging commands to explore a dump ps Lists the dotnet processes that dumps can be collected from.

[dibarbet]

The command needs to be run with the following arguments (with the appropriate processid) dotnet-dump collect --process-id <put the PID of Microsoft.CodeAnalysis.LanguageServer here>

[bobombolo]

i'm sorry i'm so dense but where do i get the PID?

[bobombolo]

i tried ls /proc but it's not there

[dibarbet]

With vscode running and the folder open, you can try dotnet-dump ps It should output something like 4148 Microsoft.CodeAnalysis.LanguageServer /home/dibarbet/.vscode/extensions/ms-dotnettools.csharp-2.0.436-linux-x64/.roslyn/Microsoft.CodeAnalysis.LanguageServer ... where the number at the beggining (4148 for me) is the process id.

If it isn't listed, that means the server isn't running and we'll have to figure out another way to get the information.

14301 lysis.LanguageServer lysis.LanguageServer -dotnettools.csharp

this one maybe

[dibarbet]

Yup! That's the one (probably truncated because the window is small).

[bobombolo]

what i get from that when i cat it appears to be a gigantic binary file

[bobombolo]

which i cannot attach here or open in a text editor

[dibarbet]

what i get from that when i cat it appears to be a gigantic binary file

Yup that is eactly what I need. A couple options for sending it

1. If its small enough to attach via email - you can send it to me at dabarbet@microsoft.com
2. If you have a cloud storage anywhere that you can upload it to, and share that link via email with me

Unfortunately we don't have a great process yet for collecting these large dump files via github :(. If none of the above options work, let me know and I'll try and figure something else out.

[bobombolo]

sending now but holy crap why is a dump file 1GB?!

[dibarbet]

sending now but holy crap why is a dump file 1GB?!

Got it - thank you! 1GB is actually on the low side for dotnet process dumps... they can get into the 20-50 GB range depending 😆

[bobombolo]

any insights now?

[dibarbet]

Apologies for the late reply, unfortunately the dump wasn't particularly illuminating here. However we've made a very large number of changes to how we start the server. Could you try the latest versions of the extension and see if you're still having issues (feel free to tag me directly in your reply)?

[TheVons]

I am having a similar issue. Will send an email with link.

[khoiCodeDump]

Hello I am also having this issue. Mine wasnt a fresh install but the problem occurs right when I was working on my project
