Raspberry Gateway freezes/hangs up

[Steven987]

Hello,
I have a Raspberry Pi (3B+) MQTT running here and one Arduino Pro mini node both with RFM69HW.
it was running for 4 days quite well and then i got no mqqt messages anymore.

So i restarted the Gateway and it worked again but only for a few hours and then it hangs up.
In the log file isnt anything usefull just an old timestamp with the last received message.
The node is sending all the time and getting NO REPLY messages in the debug.
