High memory usage in Nvim with mason, mason-lspconfig, nvim-lspconfig #48
Description
Describe the bug
When I open any buffer that is a Matlab file, the LSP server starts and has ~2GB of memory on each tmux window. Since I use many windows for different repos simultaneously in one tmux session, my RAM tends to overflow if I am not careful.
Also the language server process does not end when I just close the terminal containing the tmux session. If I close the windows individually, the corresponding processes also stop.
To Reproduce
Steps to reproduce the behavior:
- Start tmux
- Open nvim and edit a matlab file
- Open a new window
Ctrl-b + c, go to that window, repeat 1.+2. - Open
btoportopand filter formatlabprocess.
Expected behavior
I would expect the LSP to be more lightweight and not use up so much RAM?! According to the screenshot, an entire MATLAB instance is started to run the language server?!
