DuplicateHandle(in) failed (e=6)

[Lynn Lin]

Hi all
I meet a very strange issue. I use gmake 3.81 on windows 2003 and have a perl 
script to call gmake.The script is working fine if I open dos command and run 
this script.
However if I use third party tool(Jenkins ,continuous integration tool),it 
report the following error
make: create_child_process DuplicateHandle(In) failed (e=6)


Any clues would be great

Thanks
