Symptoms

A virtual machine fails with the error:

Unrecoverable Memory Allocation Failure

A virtual machine VMX core dump is generated with a name similar to:

vmware-vmx-zdump.nnn

When you try to connect to the virtual machine through a vCenter Server console, a black screen appears with the message:

Unable to connect to MKS: vmx connection handshake failed for vmfs {VM Path}

The virtual machine's vmware.log file contains entries similar to:

vcpu-0| Attempt to allocate 0 bytes of memory failed
vcpu-0| SCSI-DEV ide0:0: HBAHosted_PreIo failed for command TEST UNIT READY

vmx| Msg_Post: Error

Purpose

This article describes a specific issue. If you experience all of the above symptoms, consult the sections below. If you experience some but not all of these symptoms, your issue is not related to this article. Search for your symptoms, review Determining why a virtual machine was powered off or restarted (1019064) and Interpreting virtual machine monitor and executable failures (1019471) for similar issues, or Open a Support Request.

Resolution

This issue occurs due to non-availability of memory for the VMX process, resulting in a virtual machine failure. The vmx process was updated to resolve this issue in ESXi/ESX 4.0 Update 2.

To resolve this issue, upgrade your product installation to ESXi/ESX 4.0 Update 2 or later. For more information about the available updates, download links, and release bulletins, see the Download Patches page.
