[Qgis-user] Premature end of script headers: qgis_mapserv.fcgi

[Mayeul Kauffmann]

Hi,
When I make a query to  qgis mapserver, I get this:

[Tue May 03 01:28:58 2011] [warn] [client 127.0.0.1] mod_fcgid: error
reading data, FastCGI server closed connection
[Tue May 03 01:28:58 2011] [error] [client 127.0.0.1] Premature end of
script headers: qgis_mapserv.fcgi
[Tue May 03 01:29:03 2011] [error] mod_fcgid:
process /usr/lib/cgi-bin/rhonealpes/qgis_mapserv.fcgi(24973)
exit(communication error), get unexpected signal 11

I believe the later means the executable crashed.
I compiled it from source (recent revision from trunk 1.7) on Kubuntu
11.04 64 bits. I configure it following Tim Sutton blog here:
http://linfiniti.com/2010/08/qgis-mapserver-a-wms-server-for-the-masses/

If I modify my QGIS project by removing the password in the connection
to the postgis database, I see the following in the apache  error.log:

username: password: credentials for dbname='mydatabase' host=127.0.0.1
port=5432 sslmode=disable
message: fe_sendauth: no password supplied

so somehow the fcgi runs. Any idea?
I should mention that I could not have the symlinks work, so I copied
the fcgi in /usr/lib/cgi-bin/myproject/

Thanks for any hint!
