Memory requirement increases with each Test run

Hello,

I fail to understand, why I require more and more memory with each test-run. I thought it could be due to memory leak in my modules. Checked each module but found no such leak.

Then I tried to simulate this issue by writing a sequence file with 1 statement (x = 2 + 2) i.e. no calling of module. The result was:

The change in memory is less after 2nd test run but it is there.

What can I do to prevent increase in memory after each test run? When I have a work space with dozens of sequence files attached with few dozens of modules, this effect is significant.

Please tell me what I am doing wrong?

Regards.
