XT12 restarting amas_portstatus

[ergonaught]

I have a two pack ZenWifi Pro XT12, AiMesh, ethernet backhaul, running 3.0.0.4.388_22127. The Mesh node "randomly"/spontaneously disconnects all connected clients (2.4 and 5 GHz bands) for no apparent reason. This is always accompanied by restarting amas_portstatus ("conn_diag 2526:notify_rc restart_amas_portstatus"). The main router node never punts all connections.

I'm looking for reasons why the mesh node would do this, and what if anything could stop it.

It basically always looks like this in syslog (log_level=8; edited to remove the flood of connections; it drops all wireless connections simultaneously):

There is nothing in the main router node's syslog at this time (other than the disconnected clients connecting here instead), so it appears to be isolated to the mesh node. Hard reset of the mesh node changed nothing.
