One hour outage and recovery of Dump1090

FlightAware ADS-B Flight Tracking

Since a couple of week I see an outage of Dump1090 for about an hour at irregular times.
It happens once a week on different days.
The system recovers automatically.
In the log files I have found

Fri Oct 9 23:01:54 2015 CEST Caught SIGTERM, shutting down…
…
Fri Oct 9 23:02:25 2015 CEST dump1090-mutability v1.14 starting up.
Found 1 device(s):
0: Realtek, RTL2838UHIDIR, SN: 00000001 (currently selected)
Found Rafael Micro R820T tuner
Using automatic gain control.
Gain reported by device: 0.00 dB

Which correspondents with the time where dump1090 starts receiving messages again.

I am running:
Raspberry 2
Raspian 4.1.6-v7+
Dump1090 mutability version 1.14.
Piaware 2.1-3

Does anybody have a clue?

It seems a lot of people are having issues with piaware 2.1.3. I don’t have an answer to fix your issue, but take a look here, viewtopic.php?t=36055

You can add a crontab restart to restart the piaware every few hours.

Also, where did you get those grpahs? That looks pretty cool.

I was already considering a daily or weekly reboot but that is only when I can not find any other solution.

The graphs come from RRDTool and CollectD. I have followed this thread to setup monitoring http://discussions.flightaware.com/ads-b-flight-tracking-f21/system-monitoring-t26999.html
