@kolaf I've been having issues as well. I was running 1.5 and then 1.6-beta and now 2.0.0-beta. My setup is has 6 "SwitchMotes" from LowPowerLab, all of them with the RFM69HW radios. Given they are always powered from mains, it made sense to make them all repeaters. I have several battery powered nodes which are just plain nodes. I moved to 2.0.0-beta due to a routing loop issue in 1.6 (at least that was what the debugs were telling me) hoping that 2.0.0 would have it resolved. I cleared the EEPROMs of all the nodes and then applied the regular scripts. I watched each one boot and they all found the gateway as their parent directly. everything worked well for a few days and now the nodes have completely stopped passing messages to the gateway. I can tell visually (tx/rx led flashing nearly continuously at the SwitchMotes with no activity on the gateway) there is something looping. it happened before and a route loop ended up in the EEPROM tables, so the nodes would reboot into a loop again. I'll pull some debugs to follow this up.

Greetings! I've been trying a few things and am reporting in....

I added a 5 minute heartbeat to each of my nodes. I can see them checking in now. However the network still melts down within 24 hours. I replaced the gateway Moteino and have had the same result. The patch that @kolaf suggested basically quadrupled the functional time of the network, which is really cool. Looking at the routing each node is offering up "stale" routes to the gateway thereby creating a loop. Graphically something like this:

What I've been able to determine is that the trigger, at least a several times, is related to the gateway basically going to sleep. A power cycle and we are back in business. The cascade of the routing loop is something like this:

Now, that's two issues..

Looking at just the routing stability. does it make sense to do something like a probe to determine a route is valid before installing in the table? I've yet to review the code base, but a Time To Live in a message would also stop the loop after effectively aging out. I'm sure there is a lively discussion archived somewhere on how the routing works...

The other issue is that my gateway RFM69HW radios "appear" to be going to sleep and then i have to power cycle the Moteino to get it back on the network.. I'm wondering if there is something that is putting the radio in some sort of sleep or low power mode that it's getting stuck there...

sorry for the rambling.
