Hurm. Well, for starters, I don't think your xserver process should not be running as root. It should runs as your sdb user.
The only reason I can imagine for a -4 communication error is a problem with the xserver. Since you are trying to connect with DBMGUI, and your output below is obviously *nix, I assume the database is remote.
We can at least see what x_server is doing (if it even sees the connection) with the command:
# x_server -i -D 3 start
This will put x_server into the interactive (non-forking) mode. Then try to connect. If you could, please send the output to the list.

But when I try to register the instance on this server, I still get the "-4 communication error".

Hi Ross,
You need to start X Server. X Server is the program that facilitates network communication between MaxDB (the DBM Server) and a client. In this case, DBMGUI.
You'll need to start X Server on the machine you are trying to connect to (and of course where MaxDB is installed).
On Windows: net start xserver
On *nix: <independent program path>/bin/x_server start
Cheers, JLS

Hi there,
I have installed version of DBMGUI 7.4.3.10. I am trying to register an instance of version 7.4.2.23 but get an error message "-4 communication error".
Please advise.
