Spectrumserver doesn't like ethernet reconnect.

My spectrumserver stopped working, it didn't crash.
My modem did an unattended firmware upgrade, that it does automaticaly.

My server notices this:

However the Spectrum-server doesn't like this and doesn't recover when the network is back online.
It should check when it's gone and recover.

As the IP-address is the same, just gone for 5 minutes.

It stopped again for no reason, so I removed IPv6 and upped the FFT-size again.

Hopefully it keeps working now.

There where no messages in dmesg, only top didn't show the spectrumserver anymore.

Maybe time to make an systemd-script to have it monitored and restarted if needed.

Anyone have a script, don't want to write one if somebody has one already

Will work on this soon

I tried to install Cuda support and the same thing happened, Cuda wasn't working...

But as soon as OpenCL doesn't know the STDON/STDOUT is gone, then the Spectrum may stop.

I did found that the fft_size should be real big. Regardless of the used receiver.

At the moment I'm at 16MB, but I'm thinking it may be 256MB. Looks more like a buffer then anything else to me.
Once filled and the Spectrumserver dies.

Still testing
