The ResinConfigServer is only for the clustering configuration, it doesn't 
configure the cluster itself.  In other words, mod_caucho needs to contact a 
backend server to find out what the resin.conf looks like.  The backend server 
will send the <srun> data back to mod_caucho.  

So you really only need a single ResinConfigServer (two if you want a backup).

I'm not sure why only 4 servers show up.

If you turn on logging for the backend ResinConfigServer to "finer" (and choose 
a single ResinConfigServer so you know which machine is being used).  That 
debug data will show the srun data going back to mod_caucho, which should help 
track down the issue.

It's possible the mod_caucho cache is getting stuck, e.g. if you just added two 
new servers.  You might need to remove the cache file at /tmp/hostx_1234.

 I am trying to set up a Resin (3.0.24) cluster,  with Apache/mod_caucho load 
balancing requests to several Resin nodes. Cluster  of four Resin nodes is 
working fine, but I can't get mod_caucho to use more than  four Resin cluster 
 If using for example six nodes, with Apache  config:
          ResinConfigServer  instance1 1234
         ResinConfigServer  instance2 1234
         ResinConfigServer  instance3 1234
         ResinConfigServer  instance4 1234
         ResinConfigServer  instance5 1234
         ResinConfigServer instance6 1234
 And Resin config:
     <http server-id="inst1"  host="instance1" port="2345"/>
    <http  server-id="inst2" host="instance2" port="2345"/>
     <http server-id="inst3" host="instance3"  port="2345"/>
    <http server-id="inst4"  host="instance4" port="2345"/>
    <http  server-id="inst5" host="instance5" port="2345"/>
     <http server-id="inst6" host="instance6" port="2345"/>
      <srun server-id="inst1"  host="instance1" port="1234" index="1"  
      <srun  server-id="inst2" host="instance2" port="1234" index="2"  
      <srun  server-id="ínst3" host="instance3" port="1234" index="3"  
      <srun  server-id="inst4" host="instance4" port="1234" index="4"  
      <srun  server-id="inst5" host="instance5" port="1234" index="5"  
      <srun  server-id="inst6" host="instance6" port="1234" index="6"  

 The http://server/caucho-status page displays  correctly all the six instances 
in the "Configuration Cluster" section, but in  the "Default Virtual Host" only 
the first four nodes are listed. When checking  the Resins' statuses, only 
those four first instances are getting requests  forwarded to them.
 Am I missing some configuration parameter here, or  doing some other obvious 
mistake? I assume more than four nodes should be  possible? Many thanks for
