21.1 Legacy Series / Re: list_arp.py json high cpu usage

« on: February 12, 2021, 04:33:54 pm »

I've taken a look in the list_arp.py file and found the following area being the cause of the high cpu usage:

        try:
            record['manufacturer'] = manufacturer_mac.oui.registration().org
        except netaddr.NotRegisteredError:
            pass

Specifically the call to .registration()

What I don't know is why this is now appearing as a problem or how it should be solved.  I've commented those lines out for the time being and it prevents the periodic high CPU usage.

I’m seeing the same issue.  The list_arp.py script is being called several times a minute. If I run it manually from a shell it maxes out a single processor core for 2 to 3 seconds. I found that disabling System Configuration Daemon (configd) stops the issue happening but obviously disables some features of the web UI.
