Describe the bug

My vim randomly crashes when auto completing.

Reproduce the bug

We will close your issue when you don't provide minimal vimrc and we can't
reproduce it

I was able to have the issue by only plugging coc.nvim using vimplug in my vimrc:

call plug#begin('~/.vim/plugged')
Plug 'neoclide/coc.nvim', { 'branch': 'release' }
call plug#end()

Screenshots (optional)

[AnatoleLucet]

It also seems like a lot of coc process are draining my memory even tho I don't have any vim instance open.

[oblitum]

Your CocInfo output seems cut, there's no information on coc version and other relevant data.

[AnatoleLucet]

Because my vim crashed, I used this command NVIM_COC_LOG_LEVEL=debug NVIM_COC_LOG_FILE=/tmp/coc.log nvim <file> (that I've found on another issue) so I can get the logs after the crash.

Maybe there's a better way?

[chemzqm]

Need more info, run :CocInfo just after vim open

[AnatoleLucet]

@chemzqm there you go:

## versions

vim version: NVIM v0.5.0-dev

coc.nvim version: 0.0.79-73397d535c

request error 0 on "nvim_call_function" [ 'coc#util#win_gotoid', [ 1012 ] ] Vim(let):E315: ml_get: invalid lnum: 1 Error

Crash should be caused by this error, but don't know how could it happens.

Check :h coc_process_pid for kill node process on VimLeave

[AnatoleLucet]

Check :h coc_process_pid for kill node process on VimLeave

This is for the memory usage, right?

[jrop]

NeoVim is crashing for me, randomly when CoC attempts to display popup windows for warnings/errors (when my cursor is over the offending code).

[jrop]

(PS: this started happening recently, withing the past few days)

[chemzqm]

Unable to reproduce, try minimal vimrc or debug your neovim.

[fannheyward]

@jrop do you have any CocAction in your vimrc ? https://github.com/neoclide/coc.nvim/issues/2557

[chemzqm]

I have connection lost issue with latest neovim when typing fast, should be another issue, but we need avoid it if possible.

[AnatoleLucet]

@chemzqm it also seems like the crashes happens when typing relatively fast

I've also been getting segfaults recently. The only stuff in :CocInfo that seemed like it could be relevant was the following:

I've reverted CoC to this commit: 047a87b01d7d2df2ee1f08ef988ef419051778c1

I have not had any issues since reverting. I'm hoping to get some time to perform a git bisect, but today I've been too busy to actually perform that.

[jrop]

I've narrowed this problem down: for me other programs were hogging memory, causing neovim to not be able to allocate memory.

[Frederick888]

Possibly related: neovim/neovim#13208

[chemzqm]

I've changed BufUnload event from request to notification and make bufhidden option to hidden for buffer of reuse window.

Should be fixed now, upload the log with :CocInfo if it still happens.

[jrop]

This error just returned for me again:

I'll try updating and see if that helps.

@jrop upgrade neovim or use stable release
