I have 2Gb memory machine for Gambit, but I keep getting an abort message for not enough memory, what can I do ? is there a switch somewhere to take advantage of my memory ?

does this message appear whern you try to save the database files

It appears when I am meshing

usually when you try to save and if you try to save on c: this message appears, (this means it has to be saved in c:\folder) ,,but it seems this bug is not reated to your problem

Are you running on Windows? Windows memory management problems often give this error. If so, there is nothing you can do about it.

Yes I am running windows

You have limited options. Try doing things in smaller pieces. For example, don't mesh 20 volumes at once, but do a few at a time. Also, make sure you are using the latest Gambit release (2.2.30). It contains fixes for some things that can lead to such errors.
