If this is your longest-running job, you might have found a network 
issue where the connection between SD and DIR is dropped after some 
time of inactivity. Firewalls and routers sometimes do this...

Which versions of FD, SD and DIR are involved here?

Also, can you verify the network connection between the daemons stays 
open while the job runs?
