Installation: Registerserver not connecting

[AlexP]

Hi,

I'm on a problem installing OX on Debian (same problem on 9 or 10)

# /opt/open-xchange/sbin/registerserver -n oxserver -A oxadminmaster -P password
server could not be registered:
Server response:
error during JRMP connection establishment; nested exception is:
java.net.SocketTimeoutException: Read timed out
at sun.rmi.transport.tcp.TCPChannel.createConnection( TCPChannel.java:307)
at sun.rmi.transport.tcp.TCPChannel.newConnection(TCP Channel.java:202)

at com.openexchange.admin.console.util.server.Registe rServer.main(RegisterServer.java:91)

Someone out there, having an idea, what the problem could be?

Thanks a lot in advance

Additional:

Today, I found several error messages in ox logfiles, indicating, VM is out of memory. Maybe that's the reason for the not running registerserver.

But: The server has any ressources. 16G of RAm wich is completely free (nearly) and plenty of diskspace available.

Any idea, what to do?

I found the reason for his effect.

It was a problem with the server config, causing JVM to run out of resoures when opening too many theads.
