Then shortly after system locks up and then.

Unsure if this is bash-language-server or shellcheck issue but it started right after I updated bash-language-server today. I also opened an issue on the shellcheck github page I am unsure how to diagnose this further but thought I would mention it here.

Thank you,
Jason C.

[skovhus]

Can you please try downgrading? Not sure how you install the language server, but npm install -g bash-language-server@4.10.3 should do the trick.

[croyleje]

I tried downgrading to the bash-language-server-4.9.2-2 and it appear to be fine so I tried upgrading to 5.0.0-1 and the issue seems to have been resolved. I will do some more digging but I wasn't thinking and I updated my machine again today something may have been updated. I run the server via coc-vim so it may have even been an issue with that also sorry to waste your time. But if I find out any information I'll let you know.

[croyleje]

The issue seems to have started happening again not exactly sure what is going on I will try downgrading again and see if that fixes it and let you know.

[croyleje]

Ok I did some more testing and whatever is causing the issue seems to most reliably happen when you log into a file then make some change then save. After save it starts spawning and eating up memory looks like coc had an update in the beginning of July I am out of my area of knowledge on how to track an issue like this so Ill post what I find an again this could be an issue with one of these other applications.

[croyleje]

Ok I am fairly certain this issue is being caused by vim-coc I uninstalled coc and install youCompleteMe and used there default LSP config for bash-language-server and the issue appears to have stopped again Ill keep this config for awhile and see if anything changes if so Ill let you know.

[mystilleef]

On Neovim using the native LSP support, I have to set settings.bashIde.backgroundAnalysisMaxFiles = 1, otherwise bashls will continue to spawn shellcheck instances until my workstation crashes.

Also, the single instance of shellcheck uses close to 4GB of memory and up to 50% of CPU cycles whenever it's summoned for analysis. In other words, it severely taxes my system.

This always happens when I'm editing .bashrc/.zshrc.

[mystilleef]

Please disregard my last comment. shellcheck is spawned on every save regardless of that setting. So if you have autosave on, you're very likely to run out of memory eventually at least on Neovim. I'm not sure shellcheck is the appropriate solution for an LSP at this point.

[annahri]

Has anyone fixed this issue?

[pejato]

Am also running into this issue, downgrading to e.g. 4.10.3 does not help
