[LDM #AET-991057]: LDM 6.4.4: upstream connection closed for unknown reason

> I reduced my feeds to just CONDUIT and sent a USR2 to the pqact and ldmd

You do not need to send a USR2 signal to the pqact(1) process: only the 
downstream LDM process that's receiving data from Bigbird needs to be logging 
verbosely.
