Loranet Packet Forward Suddenly Stops

Hello…i just answer, if anyone else had the same problem, anytime.

I use packet forwarder, for data send/receive to loraserver. After 4 hours suddenly stopped.

I reset it, started it again and stopped after 2 hours again.

Had anyone the same issue?
If yes, what was the solution?

And this is a printscreen from pkt_fwd log file:


Any idea?
