I have been running an Owncloud server for about 2 years now.
Few months ago, without changing anything, I noticed my CPU was peeking at 100% all the time.
It was running on Ubuntu 14.04 and an old Owncloud’s version, so I decided to fully upgrade to Ubuntu 18.04 and Owncloud X.
My CPU issue was gone, and I was a happy man
But, the problem just came back.
My CPU is @100% since a week, mysqld is taking all the CPU, and I have now idea how to solve this.
When I do “show full processlist;”, mysql returns ~60 rows, and all is about oc_filecache.
And a simple COUNT takes between 5 and 25s, and returns more than 2 millions.
I don’t know if it’s the cause of the issue …
I tried files:cleanup but did nothing.
Can you please help ?
