Hi OttoM,

  Thanks for the tidbit!  Sure enough, the disconnected sessions are
reconnected with a lower MTU value.  My only problem now is I'm not sure
what to do with this juicy bit of information...  Is there any way I can
force a lower value from the initial connection or set a higher
tolerance for change or is that just crazy talk?  Ultimately, my goal is
to get rid of the "random" disconnects.

Thanks again,
Erin
