windbg dump command fails with error 0x8007012b

问题:

A customer is attempting to capture a minidump of a hang. He fires up WindDbg and successfully attaches to the process. WinDbg displays its header:

Microsoft (R) Windows Debugger Version 6.11.0001.404 AMD64 Copyright (c) Microsoft Corporation. All rights reserved. 

and the loaded modules are enumerated.

He enters a dump command:

.dump /m c:\problem.dmp 

It reports:

Creating c:\problem.dmp - mini user dump WriteMemoryFromProcess.Read(0x1f1e000, 0x2000) failed, 0x8007012b Dump creation failed, Win32 error 0n299 "Only part of a ReadProcessMemory or WriteProcessMemory request was completed." 

Error 0x299 is: The requested operation could not be completed due to a file system limitation

Any ideas what this means or how to diagnose?

回答1:

Have a look at the /mA switch, it was introduced with 6.10.3:

回答2:

Type net helpmsg 299, error 299 is

Only part of a ReadProcessMemory or WriteProcessMemory request was completed.

In winerror.h this is ERROR_PARTIAL_COPY

Is the process a 64 bit process? http://winprogger.com/?p=26 lists several reasons this error may occur.
