[LDM #PAE-657022]: ldm not saving data

Frank,

Is there anything relevant in the LDM log file?

Is the pqact(1) process responsible for decoding into GEMPAK files still 
running? Match the relevant "EXEC pqact" entry in the LDM configuration-file 
with the output of a ps(1) to determine the relevant process. Once you have the 
process' PID, grep(1) the LDM log file for all messages from that process. Is 
there anything relevant?
