Premature end of script headers: wwsympa.fcgi

I have a new sympa installation. The daemons are all running:

5110 ? S 0:04 /usr/bin/perl /usr/local/bin/sympa.pl
5112 ? S 0:27 /usr/bin/perl /usr/local/bin/bulk.pl
5114 ? S 0:01 /usr/bin/perl /usr/local/bin/archived.pl
5116 ? S 0:02 /usr/bin/perl /usr/local/bin/bounced.pl
5118 ? S 0:01 /usr/bin/perl /usr/local/bin/task_manager.pl

I get these errors when I try to hit /sympa:

[Thu Feb 17 14:12:42 2011] [warn] [client 75.203.133.19] (104)Connection reset
by peer: mod_fcgid: error reading data from FastCGI server
[Thu Feb 17 14:12:42 2011] [error] [client 75.203.133.19] Premature end of
script headers: wwsympa.fcgi

My apache config includes this:

LoadModule fcgid_module /usr/lib/apache2/modules/mod_fcgid.so

<IfModule mod_fcgid.c>

<IfModule !mod_fastcgi.c>
AddHandler fcgid-script fcg fcgi fpl
</IfModule>

FcgidIPCDir /var/lib/apache2/fcgid/sock
FcgidProcessTableFile /var/lib/apache2/fcgid/shm

FcgidIdleTimeout 40
FcgidProcessLifeTime 30
FcgidMaxProcesses 20
FcgidMaxProcessesPerClass 8
FcgidConnectTimeout 30
FcgidIOTimeout 45
FcgidInitialEnv RAILS_ENV production
FcgidIdleScanInterval 10

</IfModule>

ScriptAlias /sympa /usr/local/bin/wwsympa.fcgi
<IfModule mod_fcgid.c>
IPCCommTimeout 120
MaxProcessCount 2
</IfModule>

<Location /sympa>
SetHandler fcgid-script
</Location>

and in the vhost config:
Alias /static-sympa /var/www/vhosts/sympa.mkp.org/httpdocs/static_content

Can anybody suggest what I might be doing wrong?

Hi!

The web frontend and these daemons are totally independents.

ScriptAlias /sympa /usr/local/bin/wwsympa.fcgi

You use wrong fcgi script. Please follow the instructions in this page:

the web interface is the process wwsympa.fcgi.

Check your web server logs and sympa logs.

I've gotten some private messages, and this one, and I thank all those
who have sent suggestions. This one seems the most on-target, right now.

I ran /usr/local/bin/wwsympa.fcgi (and wwsympa-wrapper.fcgi) from the
command line, and both of them return a page of HTML. (This wasn't
always the case. I was still missing a Perl module.)

Now I have mod_fcgid loaded, and this in my configs:
ScriptAlias /sympa /usr/local/bin/wwsympa-wrapper.fcgi

Should I have a process somewhere, and if so, what starts it, and what
does it look like?

Thanks,

Ed

Hi Ed,

The fcgi wrapper is launched by the web server itself, however in your
list of processes, you will see the wwsympa.fcgi process running. The
only purpose of the wrapper is to make sur the fcgi is tun under the
sympa uid.

Regards,

David
