Player 4.0.1 64 bit on Fedora 16 host

[Randall20111014]

On my Fedora 16 host I have a nightly backup job that copies files on my host.

If a VMware player guest is running that job casuses a kernel panic on the host everytime.

Log from the host

[Randall20111014]

This crash was caused by the VM guest having access to files that were being backed up on the host

The fix was to stop the guest while the backup is performed.

killall -s SIGSTOP

then after backup is completed

killall -s SIGCONT
