Mapserver4.4.2 CGI version: ?Premature end of script headers: mapserv

Sat May 7 22:21:46 PDT 2005

Hi, all
I've been compiling Mapserver 4.4.2 under a linux box these days.
When using the php_mapscript, I can draw the map successfully.
While using the CGI version, I always get the same problem:
Internal Server Error
The server encountered an internal error or misconfiguration and was
unable to complete your request.
Please contact the server administrator, xxx at xxx.com and inform
them of the time the error occurred, and anything you might have done
that may have caused the error.
More information about this error may be available in the server error log.
Apache/2.0.53 (Unix) PHP/4.3.10 Resin/3.0.12 Server at 127.0.0.1 Port 80

And in /usr/local/apache2/logs/error.log I find this:
"Premature end of script headers: mapserv, referer:
http://127.0.0.1/mapserver/mi.html"

Sounds to be bad configuration of Apache? but I just can't figure out where
I could be wrong. Could someone help me? Any idea will be appreciated!

Thanks very much!!
