.hugo_build.lock: too many open files

[romeocontrol]

Hallo,
working with visualStudioCode on macOS
hugo v0.118
Error: error building site: failed to acquire a build lock: open /Users/.../hugobricks/.hugo_build.lock: too many open files

Any error on my side?
Thank you for answering!

I have never seen that before... did you manage to fix it? You can probably just delete that file.

OK,
building the complete site with hugo command works w/o error.
starting the hugo server makes the error. Deleting of /.hugo_build.lock w/o effect.

This works, but is probably not persistant.
sudo launchctl limit maxfiles 65535 200000
ulimit -n 65535
sudo sysctl -w kern.maxfiles=200000
sudo sysctl -w kern.maxfilesperproc=65535

Is this fixed? Seems like a Hugo bug, not theme specific...

Hallo,
had to pause my project.
updated hugo to: hugo v0.121.1-00b46fed8e47f7bb0a85d7cfc2d9f1356379b740+extended darwin/amd64 BuildDate=2023-12-08T08:47:45Z VendorInfo=brew
error still in place
I think, it is not a hugo bug but a problem with the system due to a too large number of open files.
Wer do these many files come from?
sudo launchctl limit maxfiles 65535 200000
still helps.
Merry chrisstmas for the all of you!

Hello,

I've the same issue using MacOS 14.2.1 (23C71) and vscode on Apple Silicon. I don't have a solution for that problem. But the workaround I'm currently using is to avoid the automatic rebuild. I simply use the command: hugo server --buildFuture --watch=false.

This isn't ideal since you will lose one of the biggest advantages of Hugo. But at least I can use the theme, which is more important for me than having automatic rebuilds at the moment.
