Hmm. Yesterday I looked over all of the datapath commits since version 1.4.3 and didn't see any bugfixes, not applied to branch-1.4, that would account for this particular message. That means that this may be a problem that we aren't yet aware of.
Unfortunately, this particular class of issue is difficult to debug. One approach that is likely to succeed, if you are willing to try it, is to do a "tcpdump" of traffic on your physical interface to a file in the background. Then, the first time afterward that you notice such a message in your log, stop the tcpdump and use "tcpdump -r<file> -n -vvve" with an appropriate filter to print only the traffic that is part of the same TCP connection as the one mentioned in the log message, and post that output (along with the log message). If you're willing to do that work (and I realize it's a bit of trouble) there's a much better chance that we can figure out the problem.
