I'm afraid I don't understand. Are you saying that data-products are being 
filed using the pathname template associated with the "^_ELSE_$" entry but that 
that entry doesn't exist in the pqact(1) configuration-file?

If the pqact(1) process is logging verbosely (i.e., logging every product that 
it processes), then a log message to that effect will occur for every such 
product. If no such log messages exists, then that product wasn't processed by 
the pqact(1) process. It must have come from somewhere else.

The only limits I can think of for your situation are that a data-product must 
be smaller than the product-queue or 2^32 bytes -- whichever is smaller.
