Andrew,

Assuming your decoders and tables are executable and readable, respectively, 
these errors probably mean that the decoder process is timing out after not 
receiving any data for some time, while the pqact PIPE action stays open, 
meaning when the pattern actions sends the next file for decoding, the decoder 
has exited.

Try adding a large timeout value to the decoder entries in your pqact files for 
each which experiences this problem:

dcmetr -t 7200 ...

Hopefully this works for you. If not let me know.
