Your English is quite good. To be honest I lost the overview about what 
interface is added where and what is connected how. Some people might be able 
to simply look at the uci config to understand the setup but I am not one of 
those.  :-)

Let me write down what I understood - feel free to correct me. 

some nodes -- node1 -- adhoc[wlan0-1] + ethernet[eth0] -- node2 -- more nodes

Each node also has wlan0 for non-mesh clients but this is of no relevance at 
this point. What is eth1 for ?

You are saying that from time to time the packets loop between node1 and node2 
using adhoc & ethernet to fly forth and back ?

You should not have loops either way but it is easy to build loops in 
complicated setups. At first we should understand your setup and 
configuration. Drawing a little picture that shows what interface is connected 
to what other interface also can help.
