[LDM #MIY-342905]: Questions about LDM 6



Charlie,

The product-queue module will not write a data-product into the product-queue 
whose MD5 checksum is identical to that of a data-product that's already in the 
product-queue. This is done to reject duplicate products and was a deliberate 
design decision.

If you must work around this feature, then I suggest including a timestamp in 
the data-product's data. This will make the MD5 checksums different for 
data-products that are, otherwise, identical.
