Is it true that Hiawatha crashes when you access the webserver via HTTPS? 
 No, only the server dont show my page, but not crashes. or show any error log. 
 Do you use a special version of Windows? 
No is the Authentic Windows XP profesional with service pack 3, with comodo Firewall,  Avira antivirus, nothing special. 
Just Hiawatha sever, with PHP fast CGI, Mysql.  I can reproduce the exact moment when error, some times is only wheni first run hiawatha link, but after 2 o 3 times the error go away abd hiawatha START with no problems, sometimes it crahes after 8 to 10 hours of use, and sometimes about 1 hour of use.
I was using LiGHTD, Nginx or Apache for windows, and was running OK for days, y asume my PC box is OK and is not a hardware Fault. 
Thanks for your time and response. 
Im want to use your server in a production enviroment,   is very secure and light.
