Thank you again Martin,

It's good to know that one is able to get 6 GB with that set up. Also I'm sorry for not being clear--I have set memory permanently to 1200m and can't set it any higher either temporarily or permanently under any conditions (through the do file or command lines, before loading data, etc). So I'm wondering if it's somehow a problem with the workstation itself.

On your machine, you should be able to allocate much more than 1200m. I have almost an identical configuration, and can set mem to 6 G w/o problems.

Your do-file could contain the line


set mem 1200m

among its first lines. Setting mem permanently does not mean that you cannot
deviate from your setting on an ad-hoc basis...

Hi,

Thanks Mark--however the settings I described are set permanently...ie
before I open the do file ...or I may not have caught your
meaning...if so I apologize and request further clarification.

I am running into the problem of "op system refuses to provide
memory". I
can't understand why.

My settings are maxvar 5000, matsize 5000, and memory 1200 MB
(Stata won't
allow me to allocate more than 1200MB either).

I run into the problem mostly while using svy commands on a large
dataset (2
million+ observations) but also when conducting merges and more
time-consuming commands, etc.
