Too many files (only on non root user)

support
1

Hello, my name is Mario and this is my first post.

I have a problem with the command hugo serve when I run it under non root permission on linux .

I checked the permission of the files : all of them have user and group to “mario” (my standard user). I checked both the files in the root folder of the site /home/mario/Projects/mio_sito_new/basic/ and /tmp/hugo_cache
I add also that it used to work flawlessly until some days ago, I did a system update but I didn’t touch the hugo installation.
The system is Ubuntu 21.10 with hugo version
Hugo Static Site Generator v0.80.0/extended linux/amd64 BuildDate: 2021-02-09T18:47:48Z (ubuntu 0.80.0-6)

I also checked the other messages in forum matching “too many files” words and I saw that the problem could be in the ulimit flag, but the output of ulimit is unlimited . Moreover the problems affected an older version of Hugo

This is the output when run with user “mario” :

➜ hugo serve

and this is the output of sudo hugo serve

Do you have any hints on how to troubleshoot the problem ?
Thank you,

If you update to a newer Hugo version (=> 0.85), you should be able to work around the problem with:

hugo server --poll 700ms

The above will use a poll strategy when watching for changes.

To fix your original problem, you need to adjust the ulimit on your system.

Thank you for the fast answer. I checked again the ulimit manual (explained in man bash) and I was mislead by the output of ulimit without parameters. Setting ulimit -n 4096 (it was 1024) solved my problem, thank you
