SER's message size limitation is 64K, which is anyway the maximum
possible udp datagram. So this is not a limitation on ser's part.

after they pass throuxrgh ser and they get fragmented (not by ser, but by
the linux network layer).
On your dump only the first fragments are shown (and that's why the
messages look truncated). If you would dump all the traffic comming from
your ser box you will see also the rest of the messages in the second ip
The asterix box should have no problem with this fragmented datagrams
(they are defragmented automatically by the linux network layer, asterix
wouldn't even now they were fragmented in the first place).
So you probably have some other problem.
