Paul,

The notifyme did exactly what it was designed too.  Notified you that the
product was sent. There is no connection to the receiving LDM.

There probaby was a message in the ldmd.log file, but not the kind you
where expecting. If you look at the log file, there would be a line
stating pqact subprocess exiting with some type of signal. Because the LDM
forks the processes the name of the subprocess and the text of the error
messages are lost. The common process of testing pqact entries is to run
the entry as stated in pqact.conf from the command line as user LDM from
LDM home. This would of caught the error immediately.
