Good point! I totally forgot to mention version numbers:

MMBase 1.7.3-final 20050107
Tomcat 5.5.15
Sun Java 1.4.2_08-b3

The only thing I could find in mmbaseroot.xml about storage is this:
<property 
name="storagemanagerfactory">org.mmbase.storage.implementation.database.DatabaseStorageManagerFactory</property>
Also, there are multicast properties in my mmbaseroot.xml. Is this also true 
for a generic MMbase 1.7.3 or did the developers who delivered this app 
fowardport the config files from an older MMbase version and thereby breaking 
certain functionality?

I added the following to my log4j.xml but I'm unable to spot any mcast 
information in the log:

  <logger name="org.mmbase.module.core.MMBaseMultiCast" >
    <level class="&mmlevel;" value ="debug" />
  </logger>

Is this correct?

The machines are on the same switch (and vlan), so a TTL of 1 should be 
enough.

Editing multicast.xml and setting a value for "multicasthost" didn't solve my 
problem yet. Also, should the port number specified in utils/multicast.xml be 
the same number specified in utils/unicast.xml? I guess not, but I've been 
wrong before.

Thanks in advance for more input!
