Does anyone also experience this problem ?

While developing, I regularly use a Windows 7 guest machine in VMWare Workstation 14 on Ubuntu 16.04 while also running Firefox 58. After a few minutes, everything freezes, both VMWare and Firefox windows then become gray, and finally VMWare crashes.

I couldn't find any relevant posts or documentation related to this problem and I wanted to know if anyone here also suffers from this kind of disturbance...
