nvim freezing

Stream: general

[Matthew Ballard]

I've been having to kill my nvim processes due to freezing about half a dozen times a day. Two questions:

• are other people having this issue?
• what is the best means of diagnosing the cause?

Thanks.

(I'm pretty sure we haven't changed anything in the extension recently, I've been super busy and haven't touched it at all)

[Julian Berman]

What OS are you on? And when things freeze can you see what process is freezing? Is it nvim itself or Lean?

[Matthew Ballard]

MacOS. nvim becomes unresponsive itself. What would Lean freezing look like?

[Julian Berman]

Seeing lean processes spike in CPU basically what was I was asking.

[Julian Berman]

What version of nvim are you on too?

[Matthew Ballard]

No spikes. 0.9.0 but it has been an issue for a few months now

[Matthew Ballard]

Anecdotally, it seems to happen when there is more load on the language server. Ie I navigate to a new line with a complicated error

[Matthew Ballard]

nvim process usage spikes and lean is 0

[Matthew Ballard]

I probably should triage my config file.

[Julian Berman]

You can possibly try dtrussing nvim if/when it happens next

[Julian Berman]

Beyond that I'm afraid I'm not a ton of help at the minute, but if you nag me slightly (and if I can manage to reproduce) I'm happy to try to diagnose when I get some spare cycles

[Matthew Ballard]

No problems. Thanks for the help.

The other thing to try by the way is :lua vim.lsp.set_log_level("DEBUG") and then share or look at the output from the LSP log file (the path is vim.lsp.get_log_path() -- but this you obviously have to do "in advance" of getting nvim to freeze, and it can get large, so ideally have a way to reproduce-ish first. And yeah np.
