As the message suggests, you are out of memory. This is not a BATMAN limit, it is a limit from the amount of RAM you have in your device.
contiguous kernel memory to store the per-interface originator data - to be more precise. See batadv_iv_ogm_orig_add_if and all kmalloc*/kfree references with bcast_own/bcast_own_sum

i observe a limit of 127 interfaces which can be hooked into bat0 where do i find this limit, or does somebody can tell me more about this? Or, if it is a good idea to circumwent this at all? Or, if its even possible in actual protocoll structure.
And we had this discussion before [1]. Not sure why you are now pretending that this never happened.
Kind regards, Sven
