help with memory consumption

["Litton, Tom - CEPM" <To...@cepm-us.com>]

To whom it may concern (if anyone),

I'm having memory problems with xalan.  I've ran it through a memory profiler and most of the memory comes from int arrays (int[]).

Most of them seem to be from the call to DTMDefaultBase.declareNamespaceInContext(int, int) (which is creating a list of SuballocatedintVector instances).  Is there any way of avoiding this call?  I've already added all the result prefixes I could to exclude-result-prefixes attribute.  

Is there anything else I should avoid doing in the XSLT, in order to save some memory?

     The int arrays in DTMDefaultBase.declareNamespaceInContext are used 
to represent namespace nodes in your input document.  The arrays are sized 
to favour documents with a small number of namespace nodes.  Do your input 
documents use a relatively large number of namespace declarations?

Thanks,
