Hi,
I put my station on-line since it is working fine (from HW point of view), but I am getting several errors on SW side now, and the results is that most of the passes are lost.
-
At every pass (at beginning of the pass) I am getting this.

Another one is the following (after that I could not get any waterfall anymore, till I reboot the PC):

I have the impression the first one is there because one of the session was not closed properly because of another error, so the address has not been released. Could it be an explanation?
The other I have no idea.
Then I am getting some more random error which I could not explain, since sometime the pass is taken, sometime not with error.
Just for info, everything is running on a Debian PC.
