Bug Check 0xE4: WORKER_INVALID

Parameters
The following parameters are displayed on the blue screen. Parameter 1 indicates the code position.
| Parameter 1 | Parameter 2 | Parameter 3 | Parameter 4 | Cause of Error |
|---|
| 0x0 | Address of worker item | Start of pool block | End of pool block | An active worker item was freed. |
| 0x1 | Address of worker item | Queue number | 0 | An active worker item was queued. |

| 0x3 | Address of worker item | Address of invalid object | 0 | An attempt was made to initialize an I/O worker item with an invalid object. |
Cause
