Which file (filetype) are u editing and what server(s) are u using?

GeekerFeng · 2023-08-23T13:12:21Z

My project. Similar to TI's SDK source code. Use c to write. and used lsp

Thanks for the info! Can you provide more information regarding the memory map of that process? Those given by pmap(1) and /proc/(Process-PID)/maps should suffice.

Current memory usage

GeekerFeng · 2023-09-11T06:04:59Z

When I closed the process, the memory saved 4G

Jint-lzxy · 2023-09-12T14:47:40Z

Looks like the problem comes from here:

7f2e2abf1000-7f2e9abf2000 rw-p 00000000 00:00 0

Some simple calculations yield:

      size: 1879052288 B [OR] 1879.052288 MB [OR] 1.879052288 GB
      perm: [R]ead, [W]rite, [-]Execute, [P]rivate
(*) source: Not mapped from a file (offset=dev=inode=0)
(*) nature: Anonymous mapped regions (blank for pathname)

So this region is probably created by mmap but are not attached to any file - that is to say, ur OS must be doing something trivial (such as using this block of memory as a new stack for some specific purposes). But I'm afraid we cant make further judgements unless u can provide detailed information (content) of this region.

GeekerFeng · 2023-09-13T02:12:09Z

Can you tell me which codes may cause this problem? I will solve this problem based on these codes.

Jint-lzxy · 2023-09-13T13:59:01Z

Can you tell me which codes may cause this problem?

Well actually this is where the problem kicks in - we have no idea where this region was mapped to (that's why it's called an "anonymous mapped region") unless u can provide detailed information (content) of this region.

CharlesChiuGit · 2023-09-13T14:37:15Z

completely random guessing here. it seems like u installed nvim via snap, can u try install nvim with other methods?
snap pkgs will sometimes have random issues here and there.

GeekerFeng · 2023-09-14T01:47:53Z

I didn't install it using snap. I'm using appimage.
I'll try upgrading nvim to see if this problem is alleviated.

GeekerFeng · 2023-09-14T02:29:25Z

I suddenly saw a prompt. The size of the prompt is the same as this memory. Is it related to this prompt?

CharlesChiuGit · 2023-09-14T02:38:02Z

I would like to know if the insane ram usage is from nvim itself or the plugins. u can open 3 terminals:
- one opening any lsp-registered random file, nvim ~/.zshrc
- one open the same file with --clean flag, nvim --clean ~/.zshrc
- one use pmap -x {PID} to see the mem usage of above two process, and show us the log.

CharlesChiuGit · 2023-09-14T02:39:26Z

I suddenly saw a prompt. The size of the prompt is the same as this memory. Is it related to this prompt?

remove that file, reopen nvim, close nvim, cat the newly generated lsp.log and paste it here.

GeekerFeng · 2023-09-14T03:28:22Z

When I rm lsp.log and reopen nvim, 13k lsp.log is generated
lsp.log

GeekerFeng · 2023-09-14T03:38:09Z

The memory is normal when nvim is just opened. It gradually becomes larger during use. I can try to reproduce it again

[ERROR][2023-09-14 11:26:01] .../vim/lsp/rpc.lua:675	"rpc"	"/home/f/.local/share/nvim/mason/bin/clangd"	"stderr"	"E[11:26:01.248] System include extraction: driver clang not found in PATH\n"

maybe try fix this issue?

other lsp.log errrors looks fine, and yeah, the ram usage looks fine from the pmap for now.

GeekerFeng · 2023-09-14T05:25:57Z

Okay, I will try to fix the clang error and continue to see if it is resolved.

GeekerFeng · 2023-09-15T03:15:41Z

I found that I might have pmap the wrong process before. I pmap the process in the red box before. Their memory is almost the same

Now I pmap the process in the yellow box, and I find that the memory is still very different.

But I only enter this one command, why are there two processes?
nvim --clean tiovx/source/framework/vx_array.c

CharlesChiuGit · 2023-09-15T03:34:53Z

the short answer is the --embed process is spawn for the non-embed host process for editing on current embedded terminal.( i might be wrong

if u use process monitor tool like btop and enable tree view, u'll see the relation between two processes.

Long answer: neovim/neovim#10071 (or neovim/neovim#18375)
