We have been noticing this on a Raspberry Pi, using a DIO for PTT control.? It happens randomly, but at a much longer timeframe - a couple weeks to a month or so.? The system is remote, so we can't physically?observe it, but we can ssh into it.? We are now logging DW's output, and also monitoring it at another station.
Just now I was able to connect to it with APRSIS32 via a KISS port, and it was receiving well and may have transmitted a packet or two from that.
In every case, simply restarting DW has gotten it going again.? The RPi itself has been up for a long time, and we don't have to reset it.
