The issue you are facing:
Since updating from 27.1.11 to 28.0.6 I encounter a lot of log entries, like:

as well as PHP errors about some size limit, that seem to have deleted themselves somehow…
I have tried to research those errors but to no avail.

Is this the first time you’ve seen this error? (Y/N):
Y

Steps to replicate it:

  1. update from 27.1.11
  2. during web updating before clicking on “proceed with web-based installer” execute occ upgrade in terminal (I “experimented” with this, as I have tried 3 times in the past 9 months to upgrade 27 to 28, but before, every time, my nc instance was not reachable so I reverted back)

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

again, see above

I am not an expert and I can provide more log entries, but they are generated every few seconds/minutes so I don’t know how I can post them without compromising myself and also if it is necessary to post all logs.
Please help me what to do.

'loglevel' => 0,

Set your loglevel back to the default (2). You currently have debug level logs on so it’ll be overly verbose.

 'mail_dobash: line 1: maint: command not found
main' => 'gmx.de',

Not sure if this was a cut and paste issue or is your actual config. If in your config, it likely should be:

'mail_domain' => 'gmx.de'

Unrelated, but memcache.local will be faster/safer as APCu[1]:

  'memcache.local' => '\\OC\\Memcache\\APCu',

Thank you for the replay, jtr!

I know I can set my loglevel higher, but I don’t understand why these entries haven’t been there before and why this should be a solution. Is this something that will get fixed or I can fix?
I have set my loglevel higher already, so my logs are not overfilling at the moment.

My mail works fine, so I don’t know for sure if I messed up smth while copy-pasting, but as it works I’m gonna leave it and maybe inspect later.

I will look into the cache later, I don’t really understand caching but I remember setting up redis with a friend in the beginning. Thanks for now.

Over night, I got more than 170 errors.
Most of them seem to be the following:
rename(/var/log/nextcloud.log,/var/log/nextcloud.log.1): Permission denied at /var/www/nextcloud/lib/public/Log/RotationTrait.php#51

The permissions for /var/log/nextcloud.log(1) are 755 www-data www-data and for /var/www/nextcloud/lib/public/Log/RotationTrait.php also.

And every few minutes I get the information:
Log file "/var/log/nextcloud.log" was over 104857600 bytes, moved to "/var/log/nextcloud.log.1"
Even though in that time only a few information and the above posted rename errors have been written. Well, it is still full, I guess.

Should I follow these instructions here to resolve that:

I have switched to APCu caching, which was fairly easy. I hope it is configured the right way. I will check later, if it affects the logs on debug level, as some logs mentioned redis.

I do get the notification about transactional file locking and that I might want to enable memcache, with redis. I am not sure if this is because the system thinks there is a high load or not. My nextcloud instance is max. used by 4 people.

I manually renamed the log and made a new one, so this problem is solved.

Now for testing purposes I enabled debug logging again and within 7 minutes, the log grew to 17kb in size again.
Most messages contain the no app in context snippet but the error messages themselves are usually unique.

Also, many of these again:
