DIRTY_MAPPED_PAGES_CONGESTION

The DIRTY_MAPPED_PAGES_CONGESTION bug check has a value of 0x000000EB. This indicates that no free pages are available to continue operations.

DIRTY_MAPPED_PAGES_CONGESTION Parameters

Parameter Description

1

The total number of dirty pages

2

The number of dirty pages destined for the page file

3

Windows Server 2003 only: The size of the nonpaged pool available at the time of the bug check (in pages)

Windows Vista and later versions: Reserved

4

Windows Server 2003 only: The number of transition pages that are currently stranded

Windows Vista and later versions: The most recent modified write error status

Cause

The file system driver stack has deadlocked and most of the modified pages are destined for the file system. Because the file system is non-operational, the system has crashed because none of the modified pages can be reused without losing data. Any file system or filter driver in the stack may be at fault.

To see general memory statistics, use the !vm 3 extension.

This bug check can occur for any of the following reasons:

  • A driver has blocked, deadlocking the modified or mapped page writers. Examples of this include mutex deadlocks or accesses to paged out memory in file system drivers or filter drivers. This indicates a driver bug.

    If Parameter 1 or Parameter 2 is large, this is a possibility. Use !vm 3.

  • A storage driver is not processing requests. Examples of this are stranded queues and unresponsive drives. This indicates a driver bug.

    If Parameter 1 or Parameter 2 is large, this is a possibility. Use !process 0 7.

  • Windows Server 2003 only: Not enough pool is available for the storage stack to write out modified pages. This indicates a driver bug.

    If Parameter 3 is small, this is a possibility. Use !vm and !poolused 2.

About “What is” service

Many of users are faced with the problem of interpreting errors that occur during the work of operating systems. In some cases, the operating system reports that an error has occurred and displays only an integer error code value. Often it is difficult to even roughly understand the cause of the error from the information given out. Our “what is” service contains a database of errors in Windows, Linux, Macos and Solaris operating systems. The database contains tens of thousands of values. In most cases, the online service will be able to help with the definition of the short name of the error and its detailed description.

Categories

Current version of service supports following types of error and status codes:

NTSTATUSMany kernel-mode standard driver routines and driver support routines use the NTSTATUS type for return values. Additionally, drivers provide an NTSTATUS-typed value in an IRP’s IO_STATUS_BLOCK structure when completing IRPs. The NTSTATUS type is defined in Ntdef.h, and system-supplied status codes are defined in Ntstatus.h.
Win32 errorWin32 error codes MUST be in the range 0x0000 to 0xFFFF, although Win32 error codes can be used both in 16-bit fields (such as within the HRESULT type specified in section 2.1) as well as 32-bit fields. Most values also have a default message defined, which can be used to map the value to a human-readable text message; when this is done, the Win32 error code is also known as a message identifier.
HRESULTHRESULT is a data type used in Windows operating systems, and the earlier IBM/Microsoft OS/2 operating system, to represent error conditions, and warning conditions.
The original purpose of HRESULTs was to formally lay out ranges of error codes for both public and Microsoft internal use in order to prevent collisions between error codes in different subsystems of the OS/2 operating system.
HRESULTs are numerical error codes. Various bits within an HRESULT encode information about the nature of the error code, and where it came from.
HRESULT error codes are most commonly encountered in COM programming, where they form the basis for a standardized COM error handling convention.
HTTP Status CodeHypertext Transfer Protocol (HTTP) response status codes. Status codes are issued by a server in response to a client’s request made to the server. It includes codes from IETF Request for Comments (RFCs), other specifications, and some additional codes used in some common applications of the HTTP. The first digit of the status code specifies one of five standard classes of responses. The message phrases shown are typical, but any human-readable alternative may be provided.
errnoInteger value, which is returned by system calls and some library functions in the event of an error to indicate what went wrong. errno is defined by the ISO C standard to be a modifiable lvalue of type int, and must not be explicitly declared; errno may be a macro. errno is thread-local; setting it in one thread does not affect its value in any other thread.
Kern ReturnApple Kernel return codes.
Ipp StatusThe IppStatus constant enumerates the status values returned by the Intel IPP functions, indicating
whether the operation is error-free.

Source code

The service is based on the open source library AllStat. Its sources are available on our git server. We will be grateful for your participation in the finalization of the library and ideas for the development of the service. You can also download ErrorLookup libraries and utilities from our site.
