Hi,
Not saying it is your problem, but the times I have seen host crashes when using VMware products was when my hardware had issues.
For example faulty RAM can trigger this type of error. Most of the time you see no problems, but every now & then when it hits that faulty chip.. strange things happen. Running virtual machines can be extra taxing for hardware and take it just a bit further than most other software will.
If you have the time then I would run hardware tests over the night as a means to exclude that hardware here is being the issue.
Once you've done that.. the next step would be to see if the host hardware has created crash dump files and inspect those for clues. There used to be a website where you could upload those, but I don't think it still exists which means that beyond the standard (checking.. yes osronline has taken down that service), you're on your own.
You can still use BlueScreenView from nirsoft or windbg.

Good luck!
