A user has reported this warning appears during core:archive.
Is it possible to make this go away?
It causes the job to fail, which then causes alerts in the user's job monitoring.

@atom-box are you able to provide some more details on the system where that happens?
We actually have configured tcpdf to use a custom path, so tempnam shouldn't throw a notice.
Did they maybe configure path.tmp to the systems tmp directory?

FYI the forum post linked here is for the same end user. I'll update this issue once I have further details on this.
For more info though, they are running Matomo on a Multi server setup.
