The mailing list for listmasters using Sympa

[<address@concealed>]

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

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>

</IfModule>

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

    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?
