Dear Alan,
thank you so much for your kind and insightful hint.
Although this does not address the contiguous memory "cap", it does
provide a way around the problem and I managed to run the xtabond2 estimations.
Thanx a lot again
Wishing you a very nice day

Roberto has already applied the Microsoft hotfix detailed here

   http://www.stata.com/support/faqs/win/winmemory.html

Several others have given some excellent advice in response to Roberto's
message.  I have only one thing to add, which might at first seem
counterintuitive.

Roberto is running out of memory in Mata, and has -set memory- to
the largest value that will work on his system.  -set memory- allocates
memory to Stata's data area.  If memory is in short supply on a system,
this, in effect, takes memory _away_ from other parts of Stata that may
need it, including Mata!

I don't know whether it will be possible for Roberto to run his analysis
on his machine under its current operating system.  However, to give
himself the best chance at being able to do so, he should _decrease_
his -set memory- allocation to as small as possible without receiving
non-Mata out-of-memory errors.  This will leave behind more memory for
Mata and give -xtabond2- a better chance to be able to allocate the
Mata matrices it needs.
