Hello, The problem is probably an infinite recursion in the XSLT stylesheet. If you want to check this yourself please execute the action "Debug scenario" instead of "Apply transformation scenario" and in the Debugger perspective execute the "Run" action to apply the stylesheet. Before that make sure that "Infinite loop detection" is set to true in Preferences - XSLT/FO - Debugger Options. If there is an infinite loop in the execution of the stylesheet you will get the message "Possible infinite loop detected". If not we need more information from your side to find the cause of the error and provide a workaround: a sample document, the XSLT stylesheet if you use a DocBook customization layer, parameters of the transformation scenario not mentioned yet (if stylesheet parameters are used, if FO processing is performed).

Implementing xincludes; when html transforming from root document everything is OK; when initiating html transformation from a nested xinclude document the following oXygen fatal error is generated via a popup dialog box:

StackOverflowError

Problem occurs from both single file and chunk modes.

Added following jvm parms to oxygen.sh to no avail:

-Xms256m -Xmx384m -Xss2m

Same problem with Xalan fop.

Advice please
