The PAGE_FAULT_IN_FREED_SPECIAL_POOL bug check has a value of 0x000000CC. This indicates that the system has referenced memory which was earlier freed.
The following parameters are displayed on the blue screen.
| Parameter | Description |
|---|---|
| 1 | Memory address referenced |
| 2 | 0: Read 1: Write |
| 3 | Address that referenced memory (if known) |
| 4 | Reserved |
If the driver responsible for the error can be identified, its name is printed on the blue screen and stored in memory at the location (PUNICODE_STRING) KiBugCheckDriver.
The system has accessed memory in the special pool which was already freed by a driver. This usually indicates a system-driver synchronization problem.
For information about the special pool, consult the Driver Verifier section of the Windows Driver Kit.
This cannot be protected by a try - except handler — it can only be protected by a probe.
