unable to fork errors

[brentkearney]

I recently updated an older version of lychee (4.0.6 I think) to 4.7.0, using the lycheeorg/lychee:v4.7.0 docker image. It seems to run, but when I try to upload a photo, I get an error: `exec(): Unable to fork [command -v exiftool].

I tried to run the "Diagnostics" feature, but I get a similar error when I click the link: exec(): Unable to fork [command -v git]. The "Logs" link shows:

Where are the logs stored on disk? I'd love to know what follows "caused by". :)

If anyone has suggestions on how to remedy or debug this situation, I would love to hear it. Thanks in advance!

I can login to the lychee container, switch to the lychee user, and run the exiftool command without problems.

root@dcdb038d19c1:/var/www/html/Lychee# su - lychee
su: warning: cannot change directory to /home/lychee: No such file or directory
lychee@dcdb038d19c1:/var/www/html/Lychee$ exiftool -h
Syntax:  exiftool [OPTIONS] FILE

Consult the exiftool documentation for a full list of options.

Why is the web server unable to fork it?

I tried switching to the lycheeorg/lychee:dev image, and got the same result.
