How many RAM did you configure for that VM? Please have also a look at #10103.

RAM was setted to 2,5GB and 3,5GB with same result.
On this week we will try to extend phisical RAM and I will tell about results.

In screen2.JPG you can see memory usage. Usage level does not increasing.
But in same time host memory is gradually filled.

We have tested Vbox with extended RAM (16GB instead 8GB).
You can see the result on last two screenshots.
VBox uses 9GB, however guest RAM is 6GB and it uses only 2,4GB max.
