Dave,

LDM 6.13.0 has better error reporting. You might have been having these errors 
before and just never noticed them.

The isolated minus sign in the command seems suspicious. Should the arguments 
"- d" be, instead, "-d"? Also, does the "logs" file or directory exist?

A PIPE entry in a pqact(1) configuration-file uses the execvp() system-function 
to execute its decoder. That function doesn't understand tilda expansions 
(i.e., "~ldm").
