Build error: EMFILE: too many open files

[davidkopp]

I have only 250 notes in my public digital garden, however, somehow that seems to be too much (I'm using an own server for the build). If I delete e.g. half of them the build works again.

ERROR: "build:eleventy" exited with 1.

There are some issues around this problem known for eleventy: https://github.com/11ty/eleventy/issues?q=is%3Aissue+EMFILE
However, with my knowledge I was not able to fix the problem.

I'm now using the following Docker / Podman build command:
