cause too much memory

[cxwx]

---

Observed behavior

it seem the ccls memory increase time by time. and If I don't close the neovim, it will cause huge memory usage. ### Expected behavior

limit the memory usage

Steps to reproduce

System information

• ccls version (git describe --tags --long): Homebrew ccls version
• clang version: clang version 16.0.6
• OS: macos 14.2
• Editor: neovim
• Language client (and version): ale(dense-analysis/ale) |nvim-lspconfig (clangd)

I observed similar errors recently. I met "Your system has run out of application memory?" errors very frequently after upgrading the ccls binary recently.

As a workaround, I switched to https://github.com/clangd/coc-clangd. You only need to modify .ccls to compile_flags.txt, or just reuse the compile_commands.json from CMake.

when using global ~/.ccls, the memory used is still very large, Is there a way to limit the ccls for global usage
