E903: Process failed to start: too many open files

[kurko]

I'm getting an error that I'm not sure its root cause is vim-ai, but it is happening when using the plugin.

I'm getting the error from the title when the plugin outputs lines to the editor, generally after the 14th line.

Here's an example prompt:

:AI write an rspec file template so I can start coding on it. the class name is SomeJob

It starts outputting code, and when it finishes line 14, it errors out with the following:

I have the same issue!

I had this issue too on macOS, but after running ulimit -n 5000 in my shell it has seemed to have gone away

No luck for me with ulimit 🙂
