by the deinstallation and reinstallation we don't have any problems.
After reinstallation and reboot from the sles11 64bit-server we have the followings error messages:
could not create ICE listening socket
cannot establish any listening sockets.
ICE Listen for connections did not return a local listener!

Data Synchronizer works correctly and the data sync with all devices

What must i do for this error messages?
