CPU consumption


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 :slight_smile:
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 ? :slight_smile:

Hi Adrien,
I see you’re running version 10.1.0 which had the exact performance issues you’re describing:
Can you go ahead and upgrade your ownCloud version?

Hi eneubauer,

Thanks, I didn’t noticed that in the changelog.
Can I upgrade from 10.1.0 to 10.2.1 directly ? Or should I just upgrade it to 10.1.1 ?



from what i have read in the past you can always jump from one major version to the next without doing the minor updates in between since ownCloud 10.
