your milter is apaprently dead, we know nothing of it.
start your milter and look at its logs.

Are you using OpenDMARC? if you do, then its because OpenDMARC is broken and 
crashes on some types of emails.

Look above those log lines for the actual crash, it looks like:

"can't read SMFIC_BODYEOB reply packet header"

unfortunately, OpenDMARC seems like a dead project so don't expect a fix, maybe 
you should prepare to move to another DMARC verification utility.

If you are not using OpenDMARC then look for the output of the milter that 
caused the 4.7.1 retry error.
