NC backup and 100% CPU by database

CocoCloud · March 29, 2023, 6:22pm

Hello, I have 100% CPU used by many DB process

I use NC 25.0.5. on debian / apache / mariaDB. It still works, but a bit slower than usual, and desktop sync fails.
According to logs, I wonder if there is something wrong with the SQLDump of Backup App ?
Any idea where I should troubleshoot first ?
I’m not sure where i can read the mariadb logs (/var/log/mysql exists but is empty) or the NC Backup app logs ?
Thanx for your help !

In NC Logs, I see many errors, I copy below only the 4 ones at the bottom (the susbsquent are probably only linked the DB being freezed)

if needed, here is my NCBackup config:

rawtaz · March 29, 2023, 8:11pm

If you are not already entirely 100% certain that it is the backup app that is causing this, you should disable that app and restart your Nextcloud instance and the database server, and see if the problem persists and can be reproduced. If it can’t, enable the backup app again and see if this triggers the issue.

This way you know for sure it’s the backup app and can then focus all of your debugging efforts on that.

jtr · March 29, 2023, 9:03pm

The suggestion from @rawtaz is a great one.

I’m not familiar with NCBackup, but definitely disable it to eliminate a significant variable in the troubleshooting process.

Here are a few questions that might also help sort things out:

Did this only start after upgrading to 25.0.5?
How did you upgrade?
What release of Debian?
What hardware platform?

CocoCloud · March 30, 2023, 4:40pm

thanks for your advice. I disabled the background job of NCBackup, and reboot → problem gone !
I will probably open an issue on the app github.

100% CPU by many database process, too many connections

Hello, I have 100% CPU used by many DB process when I enable NC Backup backgroun…d jobs. ![image](https://user-images.githubusercontent.com/115888982/228906360-3daf5175-65c3-480c-b0bc-75ebc26a52ef.png) When I disable these background jobs in the app config panel and reboot, the pb is solved. I use NC 25.0.5. , backup app v1.2.0 on debian / apache / mariaDB on Intel Nuc hardware. It still works, but a bit slower than usual, and desktop sync fails. According to logs, I wonder if there is something wrong with the SQLDump ? Is there a way to raise the app log level ? any idea to troubleshoot deeper ?
