System ca-e8WC6WPM.vacloud.us has blue screened

System ca-e8WC6WPM.vacloud.us has blue screened on 6/10 and 6/12. Another unexpected shutdown occurred on 5/31 but no debug information was available. An analysis of the minidmp files has indicated the possible root cause to be the XENUTIL.SYS driver. This is a hypervisor level component and we need assistance to determine the appropriate course of action to ensure compatibility with the underlying infrastructure.

** Is there anyone from the VA or the hosting facility who can correct this issue or let us know what version is acceptable so we can update appropriately? **

The information obtained from the debug is included below:

    This is a known issue with older versions of Xentools. To resolve this issue you will need to update to the newest version. To do this please see the following knowledge base article:

    Thank you for posting guidance. The following excerpt was taken from the article.

    “We strongly recommend backing up any important data (and possibly taking a snapshot of your server) before attempting the installation, to be on the safe side.”

    VA: we are requesting a snapshot of the CA system before we move on this. Please advise.

    Correction...

    Please provide a snapshot of this system: http://ca-4opq0mqg.vacloud.us/

    Thank you.

    Requesting a low-level operating system patch hours before a contest submission on a production system is asking the submitters to incur a significant amount of risk. This does not allow for adequate review, testing, impact analysis, etc. What provisions will the government make if applying this patch adversely affects submissions?

    To clarify, our preference is to leave the environment as it is, with the contest evaluators recognizing that machine crashes of this sort are implications of the contest furnished environment and should not be held against submissions as part of the evaluation process. (e.g., "bouncing" a machine during evaluation resulting from this virtual machine software bug)
