It isn't just "ONE TIME" for me. The extension freezes up often and completely stops giving autosuggestions or warnings, and the only way to fix it is to delete the .elixir_ls file and rebuild the database. When I say "often", I mean there are some days where I have to do that at least once an hour, and 5-15 minutes of high CPU usage every hour is just way too much to be acceptable.

I love Elixir and the ElixirLS extension is the best I've found so far, but that's not saying much. The extension has enough issues with it to make it very frustrating to work with, and even enough to make the entire Elixir experience not worth it in many cases.
