Mountion Lion Server - Network Speed Problem

[SUPERMAC512]

Hello

 

I installed an Mountain Lion 10.8.4 Server on an VMWare esxi 5.1 Server (with unlocker). Previously osx 10.7 server was installed with the same config -> They works normally (no network problems).

 

The MLion Server show in Console (Log) if afp client connected, continuous afp error (afpfs_DoReconnect).

 

What can I do? 

 

The Server Configuration is the same as 10.7 Lion Server. MLion Server was an new installation, not upgraded.

 

 

Regards
