  If the network is reasonably sparse 3000 nodes shouldn't be
  a problem - for example the network on slides 36 and 37 at
  has almost 6000 nodes.
  For a dense network you can have problems with the available
  space in your computer memory.
  Look in Pajek at number of arcs/edges in the report to
  Try to close all other programs except Gsview/Ghostscript;
  or try everything on the computer with larger memory.
  The other possibility is to reduce the size of your network:
  replace parallel links with a single link (with sum of values),
  delete some less important links - links with value lower than
  a selected threshold, ...
