gmd-ipsi XQL Engine -with large XML files

[Vipul <vv...@unwiredsoft.com>]

Hi,

Has any1 used gmd-ipsi XQL Engine?

I am currently using XQL to extract data from XML files which are about 1 to
6 MB in size. After I fire about 8-10 XQL queries, the web server gives a
'Out of Memory' error and just hangs. I am logging all the operations being
done. And at all times, the last line is the one which i print just before
excuting the XQL Query.
I checked the memory usage, and observed that the memory used by java goes
on increasing as i keep firing XQL Queries. I am setting the original DOM
Document to null immediately after I am done with the result. But still, I
guess the DOM is not being garbage collected and hence the large usage of
memory.

Does Does XQL Engine cache those results? Does XQL Engine provide any
mechanism to free resources? Can I track the resources held by XQL Engine?
What more steps should I take to preserve memory resources?
