Erik,

The "-overwrite" option wasn't specified, so incoming data-products were 
appended
to the output file. Apparently, products with WMO sequence number 330 and 331
were received in different order by the two LDM-s -- resulting in the output
files being different.

If there's more than one path from the source to the destination, then the order
of data-products can't be guaranteed.
