I am running Paralleles Desktop 10 on a MacBookAir (Mac OS X 10.9.5 / Windows 7).
Everything is fine beeing active, but returning to the computer after a period of inactivity my MacBook is often freezen: no reaction to any input, except the reset button.
I set up a complete new virtual Machine from a different Windows CD and a few programs, important for me (SAS).
I got the same error.

Dear Guna, I Thank you very much for your answer.
I will reinstall also the Parallels Desktop.
First a must finish some urgent work.
My Parallel error happens randomly. I think after a week I will have a nearly sure result.

The issue persists. After 36 hours the mac is frozen.
I wil summerise my unsuccessful trials:
1. New window virtual machine
2. Old virtual windows machine, Parallels Desktop 10 reinstalled and updated

There are some further (time consuming) trials:
3. Complete new virtual machine build with reinstalled Parallels Desktop 10.
4. Install Parallels Desktop 11, bought at then end of last year
5. Upgrade Mac OS (I use Mac OS X 10.9.5)
6. Logging the activity in Windows, but I don't know how to do it. There are a lot of protocols.

I am very very thankful for some a time sparing advice .

Yesterday I installed Parallels Desktop 11. Tomorrow I found my mac warm. The processor has been running all the night, but the Mac didn't react to any key except the reset button.

I will now upgrade from Mavericks to Yosemite, but I don't trust the new Mac OS and also not the Apple recovery. There I will prepared for a new complete installation.

I think the most important issue is now to know what happened before freezing.
In the past the Mac didn't freeze, when the Internet was turned off.
This fact I will study in more detail in order to get a statistical significant result.
