[llvm-dev] [cfe-dev] Limit clangd ram and processor usage
Hi Deep, Does your system use glibcs ptmalloc2(most linux systems do). If that is the case, there was an issue with the allocation patterns used in clangd causing arenas to continuously grow. This has been addressed in the upcoming clangd-12 release. If that's not the case, would you consider filing a bug report at https://github.com/clangd/clangd/issues please. ~ Nathan James On Tue, 2021-03-09 at 19:16 +0530, Deep Majumder via cfe-dev wrote:> Hi everyone, > I use clangd in Neovim (and CoC).

[llvm-dev] [cfe-dev] Limit clangd ram and processor usage
HI Nathan, How do I ascertain that I have ptmalloc2 on my system (I am on Ubuntu 20.04 btw). The file /usr/include/malloc.h is not the same as the file at https://github.com/emeryberger/Malloc-Implementations/blob/master/allocators/ptmalloc/ptmalloc2/malloc.h (this is the version of ptmalloc2 I found online).
