Any suggestions how to triage PROCESS_HAS_LOCKED_PAGES bugcheck?

kd2024 · Apr 8, 2024

I'm analyzing a kernel crash dump with the PROCESS_HAS_LOCKED_PAGES bugcheck. Here's what I get from WinDbg:
(I don't get all parameters for this bugcheck. Only the ones that I'm showing below.)

!analyze -show 0x76 0 0xffffaf05`5d1de200 5
Caused by a driver not cleaning up correctly after an I/O.

In this case Arg1 is 0, which means "Locked memory pages found in process being terminated".

So Arg2 is _EPROCESS or 0xffffaf05`5d1de200. When I look it up:

dt _EPROCESS 0xffffaf05`5d1de200

it gives me some user mode process. There's nothing unusual about it.

So what would be your next steps to triage this?

Oh, and here's the callstack:

I think you'll get a better response if you upload the actual dump so people on here can look at it for themselves.

kd2024 · Apr 9, 2024

Thanks, @ubuysa. I can't upload a .dmp file because of these reasons:

The client I work for will not like the idea of me uploading these dumps.
Privacy concerns of the people whose system crashed.
The dumps are usually 16GB, 32GB or 64GB in size.

At this point I can only blame a memory corruption for what I can see. That is why I am asking for advice here, in case someone has a suggestion for something else for me to try that I am missing.

The documentation already suggests what to do: Bug Check 0x76 PROCESS_HAS_LOCKED_PAGES - Windows drivers

Just open an elevated command prompt on the client machine and then enter:

Code:

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management" /v TrackLockedPages /t REG_DWORD /d 0x1 /f

Afterwards, reboot the machine and wait for the system to crash again. You could even try the !lockedpages WinDbg command too.

Hmm, thanks. !lockedpages is a good idea. I'll try. As for that registry setting, I will try it too if I have a repro. Usually I just get a crash dump and nothing else.
