I think it is..
took us ages to figure out why some client machines hit this and 
others didn't. turned out that there were MTUs on some routes that were different 
to others for various reasons.


I was considering using 
  route change (route) -mtu 1440
as a workaround, but it's a bit dependent on knowing what and where all your routes are.
