Hi there
Thanks for your input. Well, I did now reduce the numbers of CPU down to 2 and reduced the vm's RAM down to 5. This makes the application I am using difficult in handling but, at least so far, I have not experienced any stalls no more. Although I am still getting errors in the log as shown below. As long as it doesn't unexpectedly hang as before, this is some improvement for me. Still it's not a real solution for me, but for the time being until there is a fix from Vmware I am trying to work like this.

but at least the timeout issue seems to have disappeared, which seem to have caused the stalls.
Many thanks again for your continuous support!
Cheers,
