Parameters

ParameterDescription
1The session ID.
2The number of paged pool bytes that are leaking.
3The number of nonpaged pool bytes that are leaking.
4The total number of paged and nonpaged allocations that are leaking. (The number of nonpaged allocations are in the upper half of this word, and paged allocations are in the lower half of this word.)

Description

The SESSION_HAS_VALID_POOL_ON_EXIT live dump has a value of 0x000000AB. This bug check indicates that a session unload occurred while a session driver still held memory.

(This code can never be used for a real bugcheck; it is used to identify live dumps.)

Cause

The SESSION_HAS_VALID_POOL_ON_EXIT bug check occurs because a session driver does not free its pool allocations before a session unload. This bug check can indicate a bug in Win32k.sys, Atmfd.dll, Rdpdd.dll, or a video or other driver.

Remarks

The !analyze debug extension displays information about the bug check and can be very helpful in determining the root cause.
