I have the same probleme here since the upgrade to 3.5.0, so I don’t think it is a hardware issue.
I am running Raspbian 7/Wheezy, and since the update, the feeding stops after one or two days.
It seems that dump1090-fa has a problem, top says that it uses 100% CPU.
Skyview is still available, but no planes are there.
Everything was fine before for two years, power supply is an original 2A Raspberry Pi power supply, no issues with it before.
Systemctl is not available, so what to do?
