I don't that the mesh API is to blame here, the problem lies in the mesh service, giving a wrong tunnel ID to the clients for an incoming tunnel.

Cannot reproduce, the only potential source of problems was fixed in r19396.

I just got it again, ONCE, after about 30 runs. Now, it also (re)appeared after I made the VPN (re)connect faster, so maybe it now happens more often. But in any case, the issue is non-deterministic.

I get the device or resource busy always if there is already an existing gnunet-helper-exit/vpn process running. Please try to make sure that that is not the case.

It happens for 6_over and 4_to_6, looks like my system doesn't like IPv6 exits. On other news, I have been able to reproduce it once fo 4_over.
