  6. Live as usual, bug is random

Actual behavior

So at a random moment node starts to generate an extremely large number of packets around 26 packets in a second. I can see that when I wake up my node and check app logs. While all this is happening, the node sleeps and wakes up properly, but when it wakes up, it does not see any nodes in node list via MQTT (they are should be there). The admin of my mqtt server informs me that the CPU load has risen to 90% precisely because of my node. To fix this bug, you need to completely unload the application from RAM. And in order for the nodes to appear in the list of nodes, you need to click the Send node info button on your node and then the nodes will appear in the list.

Expected behavior

When node go to sleep, it sleeps. When node wakes up it should send nodeinfo_app, position_app and a telemetry_app packets, then it should update node list and go to sleep again (ofc taking into account the set sending interval)
