Describe the bug

Updated from 4.0.0 rc 2 to 4.0.0 and opencloud does not start anymore.

I'm getting this

Steps to reproduce

Update from RC2 to 4.0.0 and add missing config values
See logs

Expected behavior

Upgrade Successfully

Actual behavior

Does not start anymore anf gives me errors

Setup

I am using a custom docker compose config with user: 1500:1500

Additional context

Did not happen on RC2

There was a change in the compose project https://github.com/opencloud-eu/opencloud-compose/pull/157

Maybe that is interfering with your setup?

It appears that opencloud does not start if the UID does not exist as a username?

No I don't think so I am setting the User directive to 1500:1500 and it worked before.

That is also my assumption

Dec 01 '25 21:12 Blacks-Army

It appears to originate from here: https://github.com/opencloud-eu/opencloud/pull/1918

Specifically https://github.com/opencloud-eu/opencloud/blob/986545da524b1fddba5d2cfb0c1264f8806a8b82/pkg/tracing/tracing.go#L110

This option is equivalent to calling WithProcessPID, WithProcessExecutableName, WithProcessExecutablePath, WithProcessCommandArgs, WithProcessOwner, WithProcessRuntimeName, WithProcessRuntimeVersion, and WithProcessRuntimeDescription. See each option function for information about what resource attributes each includes.

WithProcessOwner eventually calls LookupID, which will return an error in go (https://github.com/golang/go/blob/67851547d88dbe6d7ea3aa09dcc5fa5ba94696ed/src/os/user/lookup_unix.go#L181).

Ok. thanks for the analysis. Then this is a regression.

Dec 01 '25 22:12 micbar

@butonic @dragotin This needs a backport and patch release.

Same on my case, i paste here my logs in case it helps you.

When can we expect a patch release?

I have currently shutdown the service.. should I rollback?

Dec 04 '25 16:12 Blacks-Army

When can we expect a patch release?

The patch release is already available: OpenCloud 4.0.1

Thanks a lot for testing - much appreciated!
