Alcatel Unleashed

Hello
I have a few questions about cpu load.
I tried to configure PIM for multicast. All work, but in the output "show system cpu" the "IP Stack" process loads cpu by 96% and "PIM/L2Mcast" 22%.
And few days ago the "System" process started loading 30-60% cpu.
How can I find the problem? Thanks!

Are you talking about the "CPU Usage" column in "show system cpu" output or do you mean "Capacity Usage" as they are quite different things?

You could start by looking at the latest version of the release notes for the major release of SR OS you are running for known issues in PIM.
