We have a problem where we randomly get an error message saying "Server Error",
which is generated by the Web Server. It looks like it is ndCGI that causes this
error to occur. We have used a CGI wrapper script to be able to log what is generated
by ndCGI. In there we can see that the HTML page is correctly sent and received
by ndCGI from the Application Server, but after that an exception is thrown in ndCGI.
This is the last lines that comes from ndCGI showing the exception thrown:

Run-time exception error; current exception: CORBA_BAD_PARAM
No handler for exception.
END CGI OUTPUT 5029
It looks like it is a CORBA call that goes wrong and that there is no exception
handler for this in ndCGI. This HTML file then causes a error in the Web Server,
which generates the "Server Error" page at the client. In the Web Server log
the following types of errors occurs when the "Server Error" page generated:

An interesting thing about this error is that it only occurs when we running the Web
Server and the Application Server on different machines. In our testing environment
we have both on the same machine and the error doesn't occur there but when
we use our final environment where two machines are used the problem occurs.
We have the following configuration for our machines:
Web Server:
- Solaris 2.5.1
- NetDynamics 4.1.2.
- Netscape Entreprise Server 3.5.1
App Server:
- Solaris 2.5.1
- NetDynamics 4.1.2.
- Oracle 7.3.4
Have anyone had this error and know why it occur (or at least know how to fix it)??
