we have solved the problem by setting the systemproperty java.awt.headless
System.setProperty ("java.awt.headless", "true");

Hello everybody.
We use fop.0.20.5 to produce pdf files at our linux server. It works most times. But after some times we got the following error message:
[WARNING] table-layout=auto is not supported, using fixed! Xlib: connection to "localhost:0.0" refused by server Xlib: No protocol specified
java.lang.InternalError: Can't connect to X11 window server using 'localhost:0' as the value of the DISPLAY variable.

we don't use any svg graphics and a x-server is installed on the system.
Does anyone know why the error occurs only sometimes and what we can do?
