Re: SQL Extension, memory usage
John,
After a fair amount of testing, these changes, built on top of 2.6.0
seem to have solved the memory problem. Thanks for your attention.
I will try to test new Xalan builds on a more proactive basis, so if you
have changes in the works please let me know as out products depend
heavily on the SQL extension.

I'm still trying to find that time. Unfortunately I'm also still trying to
catch up after several weeks of disruption dealing with a bunch of family
obligations...

Please respond to
xalan-dev
Phil,
I have not checked in any code as of yet. Joe Kesselman mentioned that
he might
have a few cycles to look into the code/pattern's of the core DTM code
and I was
waiting to see if we might come up with a better fix. I will send you a
note once
I have something more concrete.
