In my case, I tracked this down to either my netscreen5 or the cable into 
it going south.  It's a bit strange because other software wasn't having an 
issue, so I'll probably look at this more in the next few days.  But for 
now, removing that box from my network has made fetch happy again, which in 
turn has made me happy again.
