Release date: October 1, 2015

Summaries and Symptoms

This patch resolves the following issues:

• Attempts to provision and remove virtual machines using VIEW might fail with an error. An error message similar to the following is displayed in vCenter server logs:
  Failed to get DVS state from vmkernel Status (bad0006)= Limit exceeded" can be found. Provisioning failure with message similar to the following is displayed:
  Unable to Add Port; Status(bad0006)= Limit exceeded

• The CTK lock files (ctk.vmdk.lck) created on a changed block tracking enabled (CBT) enabled virtual machine might not get deleted until you do a clean power off of the virtual machine. This might cause issues during HA events and while running recovery software.
  You might also not be able to deploy the same template in a vApp multiple times if the template of the VM is CBT enabled. This is because CBT locks the file and is not released in time for the additional deployments.

• When you run esxtop in batch mode to export performance data into a .csv file, the exported file might not contain the vSCSI data

• When you delete a VDI environment enabled desktop pool, the VMDK files of the other virtual machine from a different desktop pool might get deleted. Multiple virtual machines from different desktop pools might affected. This happens when after deleting the disk, the parent directory gets deleted due to an error where the directory is perceived as empty, even though its not.
  An error message similar to the following might be displayed:
  014-07-23T14:08:03.408-07:00 [06072 info 'Default' opID=30545c60] [VpxLRO] -- ERROR task-19533 -- vm-1382 -- vim.ManagedEntity.destroy: vim.fault.FileNotFound:

  --> }
  --> Args
  VMDK deletion occurs, when a particular virtual machine's Operating System (OS) and user data disk are spread across different datastores. This issue is not visible when all VM files reside in same datastore.
  
• Virtual machines using VMXNET3 virtual adapter might fail when attempting to boot from iPXE (open source boot firmware).
  
• Under memory overload, an ESXi host might experience a purple diagnostic screen and fail to respond.A trace similar to the following is displayed on the host:

• When Unidesk is used in conjunction with VMview or vSphere with vShield Endpoint enabled, applications such as QuickTime might experience a slowdown in performance. This is due to an interoperability issue that gets triggered when Unidesk volume serialization filter driver and vShield driver is present on the stack.

  For each file opened by the application, even if it is just for reading the attributes, the vShield driver callsFltGetFileNameInformation;causing further processing to be performed on the files. As a result Unidesk driver opens directories that causes an overall application performance degradation.

Patch Download and Installation

The typical way to apply patches to ESXi hosts is through the VMware Update Manager. For details, see the Installing and Administering VMware vSphere Update Manager. To update ESXi 5.x hosts when not using Update Manager, download the patch ZIP file from http://support.vmware.com/selfsupport/download/ and install the bulletin using esxupdate from the command line of the host.
