Too many nested apply-templates calls Error When Running a Transformation

Problem

I'm getting the error message Too many nested apply-templates calls when I try to transform my DocBook file to HTML using default Oxygen XML Author DocBook to HTML transformation scenario.

Cause

Most likely, this is the result of a masked stack overflow error.

Solution

Try setting a new VM option with the value -Xss4m. You can also try to slowly increase this to larger values (e.g. -Xss5m or -Xss6m). Note that this consumes memory on a per thread basis (Oxygen XML Author can have tens of threads), so using a very large value here can backfire and leave Oxygen XML Author without memory.
