Grafana not responding anymore

Hello all,
after some six months since last reinstall the Grafana dashboard has stopped responding.
As far as I know I haven't changed anything since it worked.

The 1090 map works fine, 8 hours map works fine as well as graphs1090, but the Grafana Dashboard, ie (ip):3000 ,is not responding at all.

Restarting the Pi doesn't solve the problem.

Checking with netstat shows that the port is not opened by any program.

I tried restarting the Grafana-server by "sudo /etc/init.d/grafana-server start" and it tries to restart the server five times then aborts.

This is in the syslog:

I am not sure quite how to interpret the error messages, e.g., the part /usr/local/go/src/runtime, since there is no such catalogue here. The "illegal instruction" and "invalid argument" seems not positive...

Could it be that some file has been damaged or such? Can the Grafana dashboard be updated/repaired without breaking something else? I can live without the dashboard if the rest is working since I am not too exited climbing the roof right now to replace the SD-card ;-)

Any ideas is most appreciated.

Ok, thanks for quick feedback.
As I wrote, I can live without Grafana as long as the rest works but it would be great to have it working again ;-)
After all there are some interesting figures in the stats.

 

It used to work, but not anymore. It seems to find everything else fine, but it wont connect to the Internet when I hook it up to my Sony Blu-Ray player. Any ideas?
