Maybe the problem could be in the load script and not the VM. Did you tried running the load script in another machine ?
Also check with IT if the VM is configured to disable memory ballooning. The memory must be allocated to Qlik VM. Check the processor allocation, better to have some of them dedicated to the VM as well.
