It's very difficult to interpret the log messages because 1) they
appear to be the output of an "fgrep twister" command rather than,
for example, the command "fgrep 15592", which would get all messages
related to that process-id; and 2) the log messages appear to be
duplicated in blocks.

Nevertheless, it appears that both the upstream and downstream LDM
processes are working correctly (as far as I can tell).  So unless
you start loosing data, I won't be too concerned.
