unlink No such file or directory at /var/www/nextcloud/lib/private/legacy/OC_Helper.php

[Felzomah]

Since a week I get thousands of error messages about unlink no such file or directory always from OC_Helper.php, for example:

unlink(/tmp/oc_tmp_SiLd7w): No such file or directory at /var/www/nextcloud/lib/private/legacy/OC_Helper.php

{"reqId":"NLyfUvxfTXNxAKm98CTp","level":3,"time":"2024-05-21T10:15:02+00:00","remoteAddr":"","user":"--","app":"PHP","method":"","url":"--","message":"unlink(/tmp/oc_tmp_SiLd7w): No such file or directory at /var/www/nextcloud/lib/private/legacy/OC_Helper.php#200","userAgent":"--","version":"29.0.0.19","data":{"app":"PHP"},"id":"664c742c5c867"}

The error has no further calltrace.

Nextcloud version: 29.0.1.1 Operating system and version: Ubuntu 22.04 LTS Apache or nginx version: Apache 2.4.52 PHP version: 8.2

Server uses external SMB/CIFS folders. Maybe it started since updating to the new php 8.2.19.

How to proceed and to find more information to debug this error?

I have the exact same problem and was forced to disable Backup. It is probably not a PHP error since I use version 8.3 and also run into this issue. The problem behind this is the simple fact that Backup is not compatible with NC 29.x yet, which, I hope, will be fixed soon.

It turned out, that cron was running cron.php twice.
