alomost infinite loops - where to look?

[Harry Jacobson]

My server's getting bogged down with messages that appear to be looping via port 127.0.0.1. Here's a snippet from one that's been traveling around for days. Nothing strikes me as obviously wrong.

What to do or test?

Thank you,
Harry Jacobson
