Has anybody else seen this memory leak? Leads on where it's coming from? Not a runaway process, at least not that top shows up.

It isn't adhoc mode, and I can associate the two devices over adhoc and move a bunch of data with no memory lost, but turning on batman-adv seems to sink it.

The memory leak I see seems to commence as soon as a batman-adv neighbor (same version, in this case 15) appears and stops when the neighbor goes away.
Thank you very much for the hint Russel! Today I tried with one node only, but kmemleak did not report anything...
I am going to try enabling kmemleak and see of that tells me anything.
Thanks! Keep us informed!
Cheers,
