Something crashes/fails every week or so



Over the past few months, my PiAware seem to be stuck in a state where the different components stop talking to each other about once a week. Restarting the different services doesn’t fix it, but a reboot always does.

Here are my stats when in this state earlier today:

pi@piaware ~ $ piaware -v

pi@piaware ~ $ dump1090-fa --help

| dump1090 ModeS Receiver dump1090-fa v3.5.3~bpo8+1 |

pi@piaware ~ $ piaware-status
PiAware master process (piaware) is running with pid 2284.
PiAware ADS-B client (faup1090) is running with pid 12171.
PiAware mlat client (fa-mlat-client) is running with pid 15661.
Local ADS-B receiver (dump1090-fa) is running with pid 13084.

dump1090-fa (pid 13084) is listening for connections on port 30005.
faup1090 is connected to the ADS-B receiver.
piaware is connected to FlightAware.

dump1090 is NOT producing data on localhost:30005.

Your feeder ID is ad723f66-e7fd-43e0-9828-a9aa1a4f2ae8 (from /var/cache/piaware/feeder_id)

I’ve uploaded the whole /var/log/piaware.log to here:!AlUorSoxzp3ujSXMwXoKFvVzdPIF

Here are some maybe relevant lines:

Is this a known problem?



PS: This new message board software seems to be a step backwards.


No, it is not backwards, It is different.
Only a simple thing when posting code: place 3 grave-accents ``` above and below the code. The grave-accent key is left of number 1 key on US keyboard. Please see image below

post code using ``` -Typed

I have added 3 grave-accents ``` to the code part your quoted post below. See how nice it looks now!


Thanks for fixing the formatting and this very useful tip. I was looking over the available editing tools:


and didn’t see any way to change fonts to a fixed one, add indents, tables, shading, etc. It looked like my only choices were Bold & Italic. I was considering writing my post in Word, saving as .html, and pasting it in case that worked, but it just seemed a bit overkill.

It would be nice if the triple accent grave trick was discoverable via the compose toolbar. I did search in the thread on the new forum software for ‘font’ and found no hits.

Anyway, regarding my PiAware problem, as I said it is fixed with a device reboot but not a service restart. On Windows when a process Access Violates and dies, there is a .dmp file to debug. Does Linux have anything analogous that I can look for in case something is AV’ing?




Please see this thread which I have created today:

How To Format Messages in This Discussion Forum


Yes, I saw that. Thanks. It would be good if the FlightAware folks could make it a ‘sticky’ topic – if that concept exists anymore.

I’m still hoping someone will be able to address the actual issue I’m hitting. I suppose I could create some kind of cron job to reboot the PI in the middle of every night, but it would be good to find out what state it gets into and why it gets into that state.
