I've had the same Problem (independent from batmand) on some kamikaze-boxes.
You can try to enlarge the max-memory for conntrack (default is 2048):

> root@MB-1-WDS:~$ sysctl net.ipv4.netfilter.ip_conntrack_max
> net.ipv4.netfilter.ip_conntrack_max = 2048
> root@MB-1-WDS:~$ sysctl -w net.ipv4.netfilter.ip_conntrack_max=8192
> net.ipv4.netfilter.ip_conntrack_max = 8192
> root@MB-1-WDS:~$ sysctl net.ipv4.netfilter.ip_conntrack_max       
> net.ipv4.netfilter.ip_conntrack_max = 8192

append something like this to /etc/sysctl.conf
net.ipv4.netfilter.ip_conntrack_max=8192
