for example (in emacs): 1. I use treemacs to add some foobar.cljs file to my project somewhere 2. I open the file and see the contents are (ns some.package.foobar) (not sure what adds this default content) 3. I add some :require's and do something, which requires communication with clojure-lsp, e.g. try to complete (def foo (str/joi<tab> 4. Emacs freezes 5. After perhaps 10 seconds emacs unfreezes and I see completion--some: Timeout while waiting for response. Method: textDocument/completion in *Messages*

Nothing particularly interesting happens in the clojure-lsp logs at the same time:

afterwards the clojure-lsp process is still running, but the communication between emacs and clojure-lsp doesn't seem to work. And nothing appears in the clojure-lsp logs.

Running lsp-workspace-restart fixes the issue; the old clojure-lsp process dies and a new one is spawned.

I can try if I could create a minimal repro of this

Please do, This timeout should hot happen and I'm not aware of any freeze expected

Also, try to repro with the nightly build first on #clojure-lsp-builds
