STOP 0x00000041 : MUST_SUCCEED_POOL_EMPTY

STOP Errors are usually the result of a hardware malfunction or device driver issue. It is also possible to receive a Blue Screen Error due to bad system memory, malfunctioning power supply, components overheating, or hardware overclocked beyond its specification. In older versions of the Windows OS you may also receive Blue Screen Errors due to incompatible DLL files.

Since the only option when receiving a Blue Screen Error is to reboot, any unsaved data is lost. With that in mind, it is very important to eliminate these errors to protect your data.

Stop 0x41: MUST_SUCCEED_POOL_EMPTY

The MUST_SUCCEED_POOL_EMPTY stop error code has a value of 0x00000041. This indicates that a kernel-mode thread has requested too much must-succeed pool.

Parameters

The following parameters are displayed on the blue screen.

ParameterDescription
1The size of the request that could not be satisfied
2The number of pages used from nonpaged pool
3The number of requests from nonpaged pool larger than PAGE_SIZE
4The number of pages available

Cause

In Microsoft Windows 2000, only a small amount of must-succeed pool is permitted. In Windows XP and later, no driver is permitted to request must-succeed pool.

If a must-succeed request cannot be filled, this stop error code is issued.

Resolving the Problem

Replace or rewrite the driver which is making the request. A driver should not request must-succeed pool. Instead, it should ask for normal pool and gracefully handle the scenario where the pool is temporarily empty.

The kb (Display Stack Backtrace) debugger command will show the driver that caused the error.

Additionally, it is possible that a second component has depleted the must-succeed pool. To determine if this is the case, first use the kb command. Then use the !vm 1 debugger extension to display total pool usage, !poolused 2 to display per-tag nonpaged pool usage, and !poolused 4 to display per-tag paged pool usage. The component associated with the tag using the most pool is probably the source of the problem.
