Hello,
thank you for your fast reply. Some precision I use openwrt backfire and each node have eth0 bridged to bat0.
<What about the TT log? does it say something?
I do not have debug on this version, but I can re flash a new firmware. Do I need to flash all the nodes ?
wel..it would be better to have the log (yes you have to enable the debug and reflash the nodes for this...), so that we can try to understand what it is going on in that period of time.
I'm going to send to the ml a patch that will enable a more verbose log so that we can obtain more information in one shot.
Please apply that patch on top of the master branch (it should be easy with openwrt. Ask here if you have problems).
Then, it would be nice if you could copy & paste here the log obtained from two not working nodes. Once you will post the logs we will decide how to further inspect the problem. Unluckily it seems to be a arch (or what else) related problem which makes it unreproducible with my (our) routers.
Cheers,
1) the patch will follow in this thread. 2) I think it is easier to read the log than inspect the graph data 3) I just noticed this was a private mail. Please keep the conversation public so that all the other people can contribute to solve the issue ;);)
