Symptoms

You experience purple diagnostic screens that contain information similar to:

VMware ESX [Releasebuild-164009 X86_64]
#GP Exception(13) in world 4130:helper13-0 @ 0x41803399e303

VMware ESX Server [Releasebuild-123630]
#PF Exception type 14 in world 1024:console @ 0x67f0ae

Purpose

Notes:

If you have an "Exception 14" purple diagnostic screen that exactly matches the symptoms outlined in this article, see VMware ESX 3.5 Update 5, Patch ESX350-200911201-UG: Updates VMkernel, Service Console, hostd (1015025).

If you encounter a purple diagnostic screen that does not match the symptoms above, see Interpreting an ESX/ESXi host purple diagnostic screen (1004250).

If the error has not been documented within the Knowledge Base, collect diagnostic information from the ESX host and submit a support request. For more information, see Collecting diagnostic information for VMware products (1008524) and How to Submit a Support Request.

Resolution

Overview

Operating systems manage the physical memory on a system by employing several methods:

Virtual memory or paging is designed to abstract the physical memory into virtual memory. This abstraction allows the operating system to allocate memory specific to programs and allows for other forms of memory management, including Memory Swapping, Shared Memory, and Memory Protection.

Memory Swapping occurs when operating systems optimize memory by moving data that is not being used to slower mediums and vice versa.

Shared Memory is a method commonly used if multiple programs need to communicate with each other. Shared memory allows multiple programs to access the same page of memory.

Memory Protection prevents a malicious or malfunctioning program from accessing memory pages from other programs.

When a critical application has difficulty accessing memory, it generally manifests with an error involving one of these memory management operations.

Exception 13: General Protection Fault

A general protection fault (Exception 13) occurs under one of these circumstances:

The page being requested does not belong to the program requesting it (and is not mapped in program memory)

The program does not have rights to perform a read or write operation on the page

Operating systems maintain a page table that include flags to mark pages as protected. If there is a conflict between the operation and the flag, the operating system traps the illegal request.

Note: Segmentation faults are very similar to general protection faults.

This is a sample of a General Protection Fault generated by ESX:

The Exception 13 General Protection Fault may be caused by either a hardware or a software issue. As the cause may vary significantly for these types of exceptions, a core-dump review may be performed by VMware. This process is usually not possible to perform without access to protected source code and analysis tools or processes. Collect diagnostic information from the VMware ESX host and submit a support request. For more information, see Collecting diagnostic information for VMware products (1008524) and How to Submit a Support Request. You can also contact your hardware vendor if you or VMware Technical Support are able to determine that a particular driver module or device has caused the exception.

Exception 14: Page Fault

A page fault (Exception 14) occurs when the page being requested has not been successfully loaded into memory. There are both healthy and unhealthy page faults:

A healthy page fault results in the page being loaded from swapped memory to physical memory. The program is then allowed to proceed after the data has been properly loaded into physical memory.

An unhealthy page fault occurs when the page is not loaded in memory, and the operating system is unable to load the page from swapped to physical memory.

This is a sample of a Page Fault generated by ESX:

The Exception 14 Page Fault may be caused by either a hardware or a software issue. As the cause may vary significantly for these types of exceptions, a core-dump review may be performed by VMware. This process is usually not possible to perform without access to protected source code and analysis tools or processes. Collect diagnostic information from the VMware ESX host and submit a support request. For more information, see Collecting diagnostic information for VMware products (1008524) and How to Submit a Support Request. You can also contact your hardware vendor if you or VMware Technical Support are able to determine a particular driver module or device has caused the exception. To find our more about page-fault exceptions, see the Formats and Encodings of SSE2 Floating-Point Instructions table in the Intel 64 and IA-32 Architectures Software Developer’s Manual.

Note: See VMware ESXi 5.x host experiences a purple diagnostic screen mentioning E1000PollRxRing and E1000DevRx (2059053) for more information about a common cause and resolution for a page fault exception in vSphere ESXi.
