getting chunk of zero bytes in output

[Carlos Villegas <ca...@uniscope.jp>]

Hi,

I'm trying to transform a large file that contains lots of elements, 
some large CALS tables with lots of entries.
The transformation doesn't fail, no out of memory errors, but the output 
(StreamResult) contains a chunk to zero bytes, about 10KB, in the middle 
of the file: starts with with normal XML, zero bytes chunk and then 
continues with normal XML. The total file size is 12MBytes, which I 
don't think is very big.
It's only happening for a particular data file, the largest one, other 
slightly smaller files with similar complexity process correctly.
This only happens on a CentOS Linux 7, if I run it on a MacOSX, there 
are no problems.
I was using Xalan 2.7.1 but I also tested with Xalan 2.7.2 and Xerces 
2.11.0 and get same result.
I'm running with jdk1.6, tested both the default IceTea version and the 
Oracle jdk 6 and still get the same result.
I increased the heap size to about 8GB but it makes no difference, but 
anyway I wasn't getting any out of memory errors.

Any idea what could be wrong?

It's very hard to answer this kind of question without seeing the input 
and the stylesheet you're running on it. If you can make those available, 
you'll probably get answers (or at least suggestions) significantly 
faster.

(I had plans to write a "sanitizer" which would take an XML document and a 
stylesheet and remove as much information as possible from both while 
still -- hopefully -- retaining the same behaviors, to make sharing 
failing cases easier. Never got to it.)
