Parameter Description

1

Reserved

2

Reserved

3

The pointer to the hive (if available)

4

Cause

Something has gone wrong with the registry. If a kernel debugger is available, get a stack trace: the !analyze debug extension displays information about the bug check and can be very helpful in determining the root cause, then enter one of the k (Display Stack Backtrace) commands to view the call stack.

This error may indicate that the registry encountered an I/O error while trying to read one of its files. This can be caused by hardware problems or file system corruption.

It may also occur due to a failure in a refresh operation, which is used only in by the security system, and then only when resource limits are encountered.
