Well well well.
Thanks for the answers, i will do the following things:
1) To read and learn how to use the GDB :D !!
2) Compile -g3 RGPVISAServer
3) Attach gdb to a runnig RGPVISAServer process to see what is doing wrong.
Well, after finish i will publish my error, thanks for support me !!!!
Yours
Leonardo
