Subject: What does this message mean?

This message appears a _lot_ recently from one of my IOCs.
What does it mean?  (Ignore the time stamp at the beginning
of each line - that is generated by logging software.)
Obviously, a network connection has been dropped.
Why?  What I should I look for to debug this?
