Comment 47 for bug 1470250

Sorry for the long delay in posting results but I did want to share what we've learned.
1) The failures happen during the VSS Snapshot/checkpoint creation process. You can reproduce the errors by doing manual VSS snapshots.
2) The heavier the VM load, especially I/O, the more likely the error will occur.
3) Every kernel posted (including the Willy) share the same problem - differences were not significant between them.
4) During snapshot creation, even RHEL hits a bump. There's a small delay in response times but nothing that causes errors. Installing LIS 4.0 doesn't make a difference.

Unfortunately, I can't follow-up with further testing. After figuring this out we cancelled the migration to Hyper-V and invested further in our VMware infrastructure. :( Thanks!
