Hi,
Updatead my system. Just mine that went to 100% CPU on phyton3.0?

Before and after pic attached.
Note: Don't know exactly what I kill but "kill -3 73471" exited the process and CPU back to normal.
Possible to identify what's running behind a PID more that it's the phyton engine?
ps awwux | grep python
Thanks!
Here are the results.

Looks like it's related to flowd.
Found this: https://forum.opnsense.org/index.php?topic=19786.0
Tried to disable IPv6 accordingly but still, after reboot, 100% CPU.
"It's me again".
A bit more info collected from me with the limited knowledge of the inner workings I have.
Unchecking Capture Local brings the CPU usage back to normal.
Did a "search around" on the subject here and elsewhere.
The flowd log shouldn't grow bigger than 100MB according to the help text. To me they look bigger than that.
I removed the logfiles and tried with Capture Local again. Same-same, 100% CPU.

Brgs,
Logging every single packet is CPU intensive. Looks like an APU device is not qualified fir the task depending on the traffic involved.
Strange thing is that it was fine before the upgrade. Haven't seen this behaviour until the last upgrade, and NetFlow Capture Local option has been enabled since way back.
Yes the APU isn't that powerful, this is an AMD GX-412TC SOC (4 cores, 4 threads)
There is no load on the system right now, and it's only a 250Mbit/s connection for WAN (fiber). Checked and around 10-20 packets/s. Active devices on the LAN is a couple of IoTs only right now, and me navigating the firewall through ssh and https.
Attached packets/s
Brgs,
QuoteI removed the logfiles and tried with Capture Local again
its better do it with Reporting: Settings->Reset Netflow data or
configctl netflow flush
imho

And there we go!!! That SOLVED it.
I used the interface option as you gave as one way to do it. phyton peeked for a moment and then back to all normal usage.

Everybody, thank you immensely for the answers and patience going through this with me! Continue to have a nice weekend ladies and germs!
