This is normal, although if it prints it more than once, that means that the language server is restarting. And yes, I certainly wouldn’t call the setup stable at the moment. I’ve been in a bit of a crunch lately, so I haven’t even been using it myself as it’s been getting in the way more than helping.
When the server restarts, it would be great if you could capture the events immediately preceding the restart from the eglot events buffer and submit an issue on github. From there I can route it upstream to eglot or LanguageServer.jl as appropriate.
