Batmand never established a stable route for clients, ie. they never get reliable internet, actually to be honest, they get 0 internet cause routing always loops
Scenerio 30 nodes, 5 gateways, OpenWRT Trunk Batman ver 1105 batman gateway client expired
i also found this thread from before showing a similiar issue
https://list.open-mesh.net/pipermail/b.a.t.m.a.n/2007-September/000277.html
question is how do i get the routes to stabilize so the mesh functions

Please be precise here: Do you see routing loops or is your UDP connection not stable (as indicated by your log) ?

This may or may not apply here. I have a look into the code later. Do you use different hardware for your gateways and clients or always the same ?

As I mentioned before we need a tcpdump of your traffic to help you. Even better would be a wireshark log from both ends that we can analyze.

ok, im getting tcpdumps, this is a test bed of the same hardward atheros based Ubiquity NS2 devices running OpenWRT trunk 1 gateway -> 70 meters -> 1 node no batgat, batmand running it goes into this constant loop as shown in
http://pastebin.com/md162302 which is from last night 10PM
where the gateway and node continuously go into this ip expired loop for 5-15 minutes causing routing for clients to go away, and network unstability, then it appears to come back for a while
I also have 21 nodes, same hardware, running batgat which still crashed as Gustavo pointed out of which the logs were forwarded, the test bed has been setup to remove batgat and look for stability
im tcpdumping on both client and gateway now, ill forward the result of these logs in a bit as for wireshark ill make a build with that and see if i can get these logs also

Then it is not related to your hw and the link posted earlier does not help here.

Your log is pretty interesting. It shows that the basic functionality is there but does not work reliably. The gateway is sending the keep alive reply to the client which further indicates that we don't have an endianess issue here.

Do you intend to test the latest stability patches from Sven ? May be it solves your problem. It would be interesting to find out why the network is less flaky if you use the module.
