Cron Job: sh: 1: ps: not found when

[davidschuette]

I am not 100% certain where to post this issue. After some debugging and research, I hope this the right place.

Since updating to v34.0.1 I get this error roughly once per hour when running the cron job (the job is triggered every 5 min):

sh: 1: ps: not found

I was not able to determine where this ps call comes from inside the cron job. It could be one of the apps. This setup has been running without major problems for years.

This is how I call my cron job:

docker exec nextcloud-nextcloud-1 php -f /var/www/html/cron.php

At the end of this post, you can find my configuration.

Any help is greatly appreciated!

If I was to make an educated guess, it may be the serverinfo app. Though I'd expect ps to be available in that image.

[davidschuette]

I could not find a ps executable in the image using find. If you have any pointers where it should be, I could add it to PATH and fix the issue.

[DerSaxxe]

Same here but with webhosting at Netcup.
I have found this commit:

nextcloud/server@f3874e0

Maybe this solves that problem.

[davidschuette]

Seems like a related issue. Nice find!

In the meantime, I just installed procps in the container to silence the errors.
