The SESSION_HAS_VALID_POOL_ON_EXIT bug check has a value of 0x000000AB. This bug check indicates that a session unload occurred while a session driver still held memory.
The following parameters appear on the blue screen.
| Parameter | Description |
|---|---|
| 1 | The session ID. |
| 2 | The number of paged pool bytes that are leaking. |
| 3 | The number of nonpaged pool bytes that are leaking. |
| 4 | The 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.) |
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 indicates a bug in Win32k.sys, Atmfd.dll, Rdpdd.dll, or a video driver.
