High cpu on 2100 after upgrade to RC from Beta
-
@cmcdonald @marcosm It doesn't get stuck and it doesn't stop. It rotates between sed journal activity building up over 80% dropping off. Then Kea will push cpu to high level. It repeats this scenario as long as you let it. Not seeing failures anywhere. Can you replicate this?
-
We saw it in earlier beta snapshots but not since.
How many DHCP clients do you have?
Are you seeing that 30% CPU usage with the webgui open or at the CLI?
-
@stephenw10 I have under 30 dhcp clients all ipv4. Yes, on the UI screen it does jump so I looked at the long term average: I do not see long term load average of under 20% with the RC candidate. With 24.03 release, I do see under 20% long term load average fyi.
-
@applesalwaysred how long is your lease duration?
-
@cmcdonald 86400s.

In the Status > Monitoring graphs?
-
@stephenw10 sorry, I meant I have not seen under 20% cpu usage (long term) on the RC build compared to the 24.03 release where it is common.
-
Right I'm just wondering where you are checking that?
Since I don't see that on 2100s here:
-
@stephenw10 load averages on system diagnostics (at thread top) & dashboard with the 3 state state load averages. Not the current cpu usage. What happens when you add in kea with 'Enable DNS registration' and 'Enable early DNS registration' ?
-
So loads above 0.4 on the longest average?
-
@stephenw10 ~.36
-
Do you have the top output from that after it's been stable for some time?
-
-
Hmm, those php processes are the webgui displaying that. I see similar loads here.
Try running
top -aSHat the CLI without the webgui open at all. -
-
Hmm, OK. Significant.
