Steps to Reproduce


I do not have a reliable way of reproducing this currently.


It's happening fairly often (once a day for some users). I believe it may be during periods of poor internet connectivity, but I am not sure currently.


Any advice on how to troubleshoot this further or collect more information would be helpful


Environment


    

  • Host OS: Windows
    • 

  • Coder version: multiple, including v2.20.2
    • 

  • We are using Microsoft Global Secure Access which I think it an exacerbating factor, but I am still trying to determine how this interacts with what we're seeing
    •

Can you get the calling arguments of the coder.exe instances?


Can you get the parent process name?


Those might help narrow down the space of possible problems.
