Upgrading to Zenworks 11 on Sles 11 64bit got the following error.

Listening for transport dt_socket at address: 5005
libxcb: WARNING! Program tries to unlock a connection without having acquired a lock first, which indicates a programming error. There will be no further warnings about this issue.

The Zenworks upgrade 11.0 window is asking for OK. Do I continue?

The zdc was okay prior to the upgrade attempt. The server is bypassing our squid firewall.
