Hi All,
One of our applications is using FOP processing mechanism to transform xml
files to pdf format by applying XSLT templates. The issue here is (which has
become a show stopper now) is that at times the transformation process kills
the server on which it is running. This happens randomly for different
servers. There is no specific scenario in which it can be replicated. As
evident from server logs, it fails at the following line
transformer.transform(src, res);
Please find below the code snippet. Any suggestions to fix the issue are
greatly appreciated.

Source src = new StreamSource(xmlInputStream);
// Resulting SAX events (the generated FO) must be
piped through to FOP
Result res = new SAXResult(fop.getDefaultHandler());
// Start XSLT transformation and FOP processing
transformer.transform(src, res);
