There is a (somewhat arbitrary) limit on the maximum message size that
omniORB2 will send or receive. The default is 2Mbytes. This limit is to
protect the ORB against rogue IIOP packets.

The limit can be changed using 'void omniORB::MaxMessageSize(size_t)'. Its
current value is returned by 'size_t omniORB::MaxMessageSize()'. These
functions are all documented in the user guide.

By the way, you will get maximum marshalling efficency if you transfer your
data as sequence of octets or other primitive types.
