NCP 1.50.3: Nextcloud check - error

ℹ️ Support 📦 Appliances (Docker, Snappy, VM, NCP, AIO)

My NCP suddenly stopped working.
First I got a message on screen that it was in maintenance mode.
I still could get into the NCP panel, but it did not react to any tries to beoot via the UI.
It already said “Nextcloud check - error”
Then I unplugged the pi and restarted it.

Now the login screen is gone and only says “service unavailable”.

I still can get into NCP Panel, which shows:
Nextcloud check error
HPB service down

Rebooting did not help.

I do not know what that segmentation fault means.

Anyone with any tips on how to restore my NCP?

Got the similar error, since this week.
Plus can not start mariaDB.

Maybe it’s unrelated, I do not know.

So, I do not know what happened.

Since the raspi still works and I even can get into the NCP Admin panel I could check the logs.

It does seem that for a couple of days there have been two errors.

“Cannot load Zend OPcache - it was already loaded”

“/usr/local/bin/ncc: line 3: 76294 Segmentation fault ${SUDO} php /var/www/nextcloud/occ “$@””

The first one I now was able to fix by following PhP warning - Cannot load Zend OPcache - it was already loaded · Issue #416 · nextcloud/nextcloudpi · GitHub by deleting the two 20-opcache.ini files.

My raspi is now on PHP 8.1 and a short while ago I did manually upgrade the raspi which seems to also have updated PHP.

I currently assume this PHP upgrade to 8.1 is the reason for everything.

The segmentation faults are still there though.

This here might be a clue: Service Unavailable after update
“delete the new opache folder and all is good”
I do not know what to do exactly though.

Found this: HPB Down, nothing helps - #3 by sven1234

sudo bash -c 'source /usr/local/etc/library.sh && clear_opcache' 
sudo service php8.1-fpm restart

This did replace the service unavailable screen with the into screen that tells me NCP is in maintenance mode.

And today it really was in maintenance mode (I saw the checkmark in the panel).

After disabling the maintenance mode my NCP now is running again!

The bad news is that I now seem unable to do a backup.

[ nc-backup ] (Wed Nov 23 17:33:36 CET 2022)
check free space...
/usr/local/bin/ncc: line 3: 14099 Segmentation fault ${SUDO} php /var/www/nextcloud/occ "$@"

Solution was a simple hardware upgrade with more RAM memory.
These segmentation faults basically mean “out of memory”.

NON è così…
