MLAT working, but dump1090 crashing


I’m trying to troubleshoot why I’m no longer reporting positions. dump1090 appears to be crashing, although I believe I’m on the latest software. Reboots have not helped. This is what’s in my log:

[2018-11-28 13:06 EST] lost connection to dump1090-fa via faup1090
[2018-11-28 13:06 EST] faup1090 exited with SIG SIGSEGV
[2018-11-28 13:07 EST] Starting faup1090: /usr/lib/piaware/helpers/faup1090 --net-bo-ipaddr localhost --net-bo-port 30005 --stdout --lat 42.425 --lon -83.902
[2018-11-28 13:07 EST] Started faup1090 (pid 990) to connect to dump1090-fa
[2018-11-28 13:07 EST] lost connection to dump1090-fa via faup1090
[2018-11-28 13:07 EST] will reconnect to dump1090-fa in 30 seconds

Is there more info I can post that can help with troubleshooting?

Thanks, Chris


I should add that this started happening nearly a month ago, on Nov 9th. I hadn’t changed anything, it’s just been sitting there running successfully and then stopped.


try to reinstall piaware.

sudo piaware-config

Copy down the feeder id you will need it after the reinstall
(and other settings you want to set again)
Also updating the system doesn’t hurt.

sudo apt update
sudo apt upgrade
sudo apt purge piaware
sudo apt install piaware

Then you can put back the feeder id and maybe other settings

sudo piaware-config feeder-id xxx-xd23-xxx.-asdsf-xxx

What is very curious though is that MLAT still seems to be working.
I have no idea how that could be.
You can also try to purge and then reinstall dump1090-fa.
If you have any changes in the config file you might want to note them down first.


What hardware & sdcard image is this on?

(nb: this looks like a faup1090 - part of piaware - crash, rather than a dump1090 crash)


This is a Pi Model 3 B v1.2 and a Pro Stick Plus v1.0. The image is whatever I downloaded from here in May of this year. I’m not near the hardware at the moment, but can check.


Well, I couldn’t get my setup to reboot after trying to update everything so I started from scratch with a fresh install of all of the most recent everything.

I’m back up and everything now looks normal. Not sure what happened, but it appears that my SD Card was probably corrupted and maybe that had something to do with it. I’ll investigate that later.
