"unknown process" issue ?!

So I’m reading about the upgrade to 6.0, and the grey gear icon, and I see the recent logs (yeah I’m a set it and forget it mostly on these things), and I notice there are several entries of
Started faup978 (pid 21936) to connect to unknown process and

which are all before updating, and then the following afterwards…

Have two dongles connected, powered by a 12vdc to 5vdc converter off a 10 amp power supply, two antenna’s, and apparently I’ve botched SOMETHING in the config somewhere (as usual)

Any idea (looking at you ABCD567 haha) what/where/how I’ve done wrong?

Thanks for any ideas, I’ll try to reply with whatever info you ask for as quick as I can

Is this a PiAware sdcard or something else?

SD card on pi fresh image 14 Aug, last card died… at the beginning I’d swear it said everything was fine, so I stopped checking everything…

Right, but is this a PiAware sdcard image or some other image with a package install?

The “unknown process” implies that sudo (or netstat) isn’t working right; the “connection timed out” in earlier logs implies that there’s something wrong with networking. Neither should happen on a piaware sdcard image.

If this is a piaware sdcard image I would suggest recording your config then reimaging.

it’s a piaware image from this website.

The “connection timed out” section you’re talking about is internal IP address connection to the internal port

[2021-09-04 04:37 EDT] faup978(20451): connection to [::1]:30978 failed: Connection timed out
[2021-09-04 04:39 EDT] faup978(20451): connection to 127.0.0.1:30978 failed: Connection timed out

It looks like the [::1] is trying to reference IPv6, while obviously 127.0.0.1:30978 is IPv4

For some reason faup978 isn’t communicating with the rest of the program for some unknown reason, but the 1090 is working fine…
