How much heap space did you allocate?
My usual rule of thumb is 5x the raw document size, so this should run if
you allocate 1Gb (use the -Xmx option). That's an apporximation of course,
it's sometimes more, sometimes less.

Subject: [xquery-talk] Saxon: Java heap space problem
When attempting to process a 200 MB file with Saxon 8.9J (Java version
1.6.0_01), I run out of heap space.
Building tree for file:/D:/PFA/PFA_200509302000_F.xml using class net.sf.sa
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
Since I'm already using the default "tiny tree" model, and having closed
down other applications, short of adding more physical memory, is there
anything else I can do? If it matters, this large file is only 2 "lines":
the XML declaration and the rest of the file.
Is there anyway of getting a ballpark handle on the max size of file I can
process with Saxon (and Java) if my physical memory is say "N" MB?
Total Physical Mem = 2.048 GB
Available Physical Mem = 1.22 GB
Total Virtual Mem = 2.00 GB
Available Virtual Mem = 1.96 MB
Page File Space = 3.85 GB
