Data feeding is not related to AJAX, but map display is.
Sure dump1090 or piaware has stopped if you received an outage alert email from Flightaware.
There was no dc power fed from dc-adaptor/RPi/USB port to the “Triple Filter LNA”. However this argument is weak as the dc-adaptor/RPi/USB port were earlier supplying power to integral LNA of Pro Stick Plus without any issues. Is there a big difference in power requirement of Pro Stick Plus vs NooElec SmarTee+Triple Filter LNA?
The rtl-sdr triple filter LNA is kinda power hungry and at 5 V will draw 150 to 200 mA.
I never get that message for tar1090.
Is it a recent version?
Also i don’t think this was about momentary flashing … outage mail and all.
It happens occationally and been there for long time. But I’m running tar1090 on different box than dump1090. I thought tar1090 box loses connection to dump1090 sometime.
So that sounds like a lighttpd option is missing:
server.stat-cache-engine = "disable"
But my tar1090 install script should take care of that.
At least the flashing of that message does occur regularly without that option.
But i’d suggest to move this to another thread as this thread is about a different issue.
It looks like dump1090 froze again:

This is a hardware problem, dump1090 can’t talk to the dongle.
Might this suggest that the Nooelec SmarTee is defective?
New dongle has been installed. We’ll see if the issue duplicates.
