100% CPU by many database process, too many connections #513

Open potagerGit opened 1 year ago

potagerGit commented 1 year ago

Hello, I have 100% CPU used by many DB process when I enable NC Backup background jobs.

image

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 ?
