I have a large DOT file that I am trying to graph in GraphViz using DOT. I used the following command:
`dot -Tpng -o d:\GUIForm\test2.png d:\GUIForm\graph_2291547484206256890.dot.tmp`

I got the following error:

`Error: Edge length 65873.000000 larger than maximum 65535 allowed. Check for overwide node(s).`

The syntax of the DOT file is correct but there are 230k lines in the DOT file (it is a function call graph). Any idea to circumvent this error? Or is there a hard limit on the size of files that GraphViz can handle?

Thanks.
