SG5100 CPU spike every 2minutes from 3 to 100% after update
-
Hi
After the upgrade of my 5100 from an older version (21 or 22) to 23 or 24 I notice I higher CPU usage from 3-5 to 12-16 and CPU spike to 100%, most of the time resulting in a frozen web interface and my vpn connection was disconnected for 10 to 20 seconds.
I upgrade to 24.11 but same behavior, I try to remove all the Interfaces widget keeping just Sys Info, Services and Gateway.
The CPU came down to 3% but precisely every 2min I have a 100% CPU spike
I have the following packaged install:
aws-wizard
ipsec-profile-wizard
openvpn-client-export
WireGuardI stopped the wireguard service but no change
I have a dozen of client who connect with open vpn and an open VPN link (this 5100 is the client) with another 5100 but before I never had any issue and the linked 5100 is working in the same package and users condition but has no spike issue with a 8% CPU average and was as well upgraded to 24.11
Anyone could help?
Thanks

Check the System Activity page or (better) at the CLI run
top -HaSPand see what's using that CPU when it happens. -
@stephenw10 thanks for your reply stephennw10, I have the following my running top -HaSP

Hmm, that output looks as expected. There is no significant CPU load shown.
Does it only appear when checking the dashboard in the GUI?
