"kworker/4:1+events_freezable" runs every hour to clean buffer

pkr

I have a VPS with 32gb RAM and 8vCPU. The VPS is mostly idle (SAR %idle= ~99), but "kworker/4:1+events_freezable" runs every hour and cleans the buffer. As a result of this, my website becomes a bit slow for some time. I am using Debian10 OS and have installed MyVestaCP as the control panel.

Is there any way to stop "kworker/4:1+events_freezable" from running every hour?

Do you have any more details about the process that runs to clear the buffer?

kworker refers to any running kernel process and events_freezable is a rather generic indication of which task is running, I can't see anything that might be helpful information in this case.

Also, while I haven't used MyVestaCP (Or heard of it, actually), I have never encountered this issue on a Debian 10 installation, my buffer has always worked as intended.

Thanks for your input. My host was running some job to clean the buffer. They have stopped that job now.

What's your host? I would like to ask them how often they do that buffer cleaning...

if you have the debug symbols for your kernel and linux-tools (if using a repository you should) you may be able to use perf to identify what is happening. Perf will show you whats large function calls are being made through event sampling.
