"kworker/4:1+events_freezable" runs every hour to clean buffer
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 andevents_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.
I recommend Hetzner Cloud (Referral - €20 free)
I have servers at Hetzner, Scaleway and BuyVM
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...

hahahahahaha
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.Latest Offer: Brazil Launch 2020 Offer
