Are you getting a whole bunch of HTTP HEAD requests from
those same visitors?  I've seen that from Mac/Safari (well,
we *think* Mac/Safari.  It's possible it could be WWW::Mechanize
or something similar using a spoofed UA -- but the behavior
usually looks more like human browsing with a browser that
stupidly likes to check all links on each page visited).

Interchange currently treats HEAD basically the same as
a GET -- which means those visitors might get strange
results since it is as if they were clicking every link
on every page they visit, as far as the Interchange session
is concerned.
