The log messages you are looking at are harmless. Thanks for providing the whole log... it shows that you should have received a more relevant error message on the screen at the time of the failure:
2017-05-06T11:08:41.587-04:00| vcpu-3| E105: PANIC: Semaphore 1000 wait failed: 257
This is a recently-discovered compatibility issue between the VMware Workstation and the very latest "fast ring" releases of Windows. We have determined that a function in Windows has changed its behavior in a way that no longer corresponds with its documentation and which causes VMware Workstation to occasionally fail in this way. We're investigating a workaround as well as reporting the problem to Microsoft. Until the problem is resolved (either in a new build of Windows or a new release of VMware Workstation), you may need to roll back to an earlier Windows build.
Hi again fsouza_in,
VMware Workstation Pro and Player 12.5.6 have been released, and contain a workaround for the "Semaphore nnnn wait failed: 257" compatibility issue affecting Workstation running on Windows 10 Creators Update.
Please let us know if you continue to encounter "Semaphore nnnn wait failed: 257" errors after applying the update.
