David,

  This may or may not help.  We had problems with some of our NT boxes
getting intermittent problems like you describe.  IBM suggested that we
halve the TCPBUFFSIZE & TCPWINDOWSIZE options in our dsm.opt.  Our problems
seemed to be with older client code, which does not match with your
problems.

Good luck,
  Dan T.
