I just fugured out, that alfresco tries to generate a new RMI registry after 4 Minutes

11:32:51,190 INFO  [org.alfresco.repo.dictionary.DictionaryDAO] Registered namespace 'http://www.w3.org/XML/1998/namespace' (prefix 'xml')

But ends up in a ObjID already in use error

I must admit that I should have paid closer attention to the other threads with similar problems. The final solution was a wrong entry in the /etc/hosts file.


# /etc/hosts
# Auto-generated file.  Keep your customizations at the bottom of this file.
127.0.0.1        localhost localhost.localdomain
xx.xx.151.66     root86.localdomain root86-eth0.localdomain root86-eth0
#xx.xx.148.53     root86.localdomain root86-eth0.localdomain root86-eth0
#END of auto-generated code.  Customize beneath this line.

just double check your own ip with ifconfig 😎
see this thread for further information

Note that DNS problems can be very subtle.
For example, if you try to run on a machine that is served by DHCP
that hard-codes an IP address in an /etc/hosts file, and that hard-coded
IP address happens to not match the one given to you by DHCP,
then Spring's RmiServiceExporter will end up trying to bind to
an IP address that may not correspond to a network device.
If that happens, then the bind will get refused, a registry at the
*default* RMI will get created because Spring's RmiServiceExporter
makes a "best faith effort" by failing over to localhost but it won't
get any of the other settings that prevent conflicts downstream.
When those conflicts occur, you'll get "ObjID already in use".
Whew!

When in doubt, check your network interface's ip address
using something like ifconfig on unix, then ping your hostname
and see if the addresses match. Also, remember to inspect
your process list for lingering Tomcat instances. Another useful
tool on unix if some other process is causing trouble is 'lsof'.
