Opening nodejs project in VS Code creates node zombie processes

[davidwincent]

Type: Performance Issue

$ yarn create next-app --typescript node-zombie $ cd node-zombie $ code .

Wait a few hours, usually the problem happens in the end of the day.

When filing this report I have:

• disabled all extensions
• closed all vs code editors
• closed all vs code terminals
• no other vs code windows open

I have 2 node-processes consuming 100% cpu each,

This is the information shown in Activity Monitor:

@Tyriar Based on ptyhost.log, could these be terminal processes?

[meganrogge]

to be clear, are your first two steps taken in an integrated terminal within VS Code?

[davidwincent]

to be clear, are your first two steps taken in an integrated terminal within VS Code?

No, the third steps open vs code

[davidwincent]

One theory is that kill terminal in vs code (trash bin icon or command-backspace) does not send any signal to terminate the terminal processes?

I am using the builtin JavaScript debugger to launch npm script with local development server. Stopping the server with ctrl-c instead if kill terminal seems to work better.

[meganrogge]

I looked into the code and seems like we do the right thing here.

I also looked at the process explorer and killing the process via ctrl+c or the trash button have the same effect.

could you make a gif of the process explorer next to the vs code window when this happens?

This issue has been closed automatically because it needs more information and has not had recent activity. See also our issue reporting guidelines.

Happy Coding!

[davidwincent]

Not sure if coincidence, the problem seems to be removed after I started using ctrl+c instead if kill terminal.

I am using Concurrently in my dev script, maybe this package has some sigterm/cleanup issues?
