My bad, nothing useful on that log.

I kind of reproduced the problem:

forcing nextcloud cron job to execute when mysql is not running
[root@server ~]# systemctl stop mysqld
[root@server ~]# sudo -u apache scl enable rh-php72 -- php -dmemory_limit=512M -f /usr/share/nextcloud/cron.php

So an explanation or sequence of events could be that:

  1. mysqld service was stopped or restarting
  2. then, the nextcloud cron job ran
  3. cron.php failed to connect to mysql’s unix socket
  4. cron job failed and mailed the error
  5. after that, mysqld service was back online, no more errors and nextcloud still works

My Nethserver restarts every morning at 07:45. The mail with the error message came at 07:50.
I think it’s because the restart and cron job are temporally together. Could that be a possibility?

Yes, that plausible, according to mariadb/mysqld service:

Just compare the timing between the cron job execution and mariadb/mysqld service start.

Is it possible to terminate the cron job to a later time?

The nextcloud cron job is set to run every 5 minutes. I don’t see the need to change it, if our findings are correct the message can be ignored.

Ok, thanks to you and all the other helpers.
