DCD Server keeps running in the background with 30% CPU load, seemingly doing nothing

[Rojetto]

This happens with version 0.13.1, both using the D plugins for Visual Studio Code and Intellij. I'm only using the editor frontends, so I unfortunately don't even know where to start looking for the problem. I'd be happy to provide more specific info if you tell me what you need.

Thanks for the suggestion. I just switched, but it only made things worse. The extension automatically installed DCD Server version 0.13.2. When opening my project I now get an error every few seconds saying „Could not initialize DCD for “. Here's what's in the log (it just keeps filling up like that)

The project is open source, you're welcome to to try it out yourself here.

Using the workaround you proposed it now works. The weird CPU load is gone, and it also doesn't seem to randomly crash anymore, as it did on stable.

Thanks for investigating this, I would consider this resolved from my side!
