Terminate action option not working

[teognost]

tested on that box -it is ok.
But now I think the VB process itself would freeze sometimes as it happened that at different steps (for example running a VBscript step)the build simply does not do anything ,does not write in the log ,does not advance ,nothing
The steps where the issue appear are random.
And about the step where I have timeout of 5 hrs -every time is the same ,the step is not terminated after 5 hrs ,it remains hanging.
The box where these issues appear is a virtual machine -can be this a cause?
On my normal machine nothing like this happens.
But I need to understand what is causing these issues on virtual machine and how to fix it.
