I am using Saxon 6.5.5 version. I get the below error while parsing large XML
documents (~ 80 MB). My JVM Initial Heap Size and Maximum Heap Size are set to 512 MB
and 1024 MB. Any idea what is causing this? Any help on this issue would be appreciated.

I would suggest trying it on Saxon 8.9. I'm not saying that will solve your problem,
but it may provide better diagnostics. Run with the -t option to get information on the
size of the tree. It's useful to construct smaller documents and measure how the memory
usage increases as the document grows. That will help you to see where the limits are
and how much memory to allocate. Every document is different: the general rule that you
need 5 times the source document size (so 400Mb in your case) is just a rule of thumb.
