ethernet -> imagen hangs vax

[john salmi]

Help!  We seem to have a problem with tcp/ip.  Just got our ethernet,
did the install, and tried it out.  Sent files to our Imagen, which decided
to hang our 750 after ~3 file transfers.  Had to reset to get our Vax back.

Anyone else ever experience this?  Called Imagen and got the "Du-uh, I really
don't think I can help you" routine.  Answers?  Definative solutions? 
Questions?  Anyone got a gun?
