Bug Check 0x27: RDR_FILE_SYSTEM
The RDR_FILE_SYSTEM bug check has a value of 0x00000027. This indicates that a problem occurred in the SMB redirector file system.
Parameters
The following parameters are displayed on the blue screen.
| Parameter | Description |
|---|
| 1 | The high 16 bits (the first four hexadecimal digits after the "0x") identify the type of problem. Possible values include:
0xCA550000 RDBSS_BUG_CHECK_CACHESUP
0xC1EE0000 RDBSS_BUG_CHECK_CLEANUP
0xC10E0000 RDBSS_BUG_CHECK_CLOSE
0xBAAD0000 RDBSS_BUG_CHECK_NTEXCEPT
|
| 2 | If RxExceptionFilter is on the stack, this parameter specifies the address of the exception record. |
| 3 | If RxExceptionFilter is on the stack, this parameter specifies the address of the context record. |
| 4 | Reserved |
Cause
One possible cause of this bug check is depletion of nonpaged pool memory. If the nonpaged pool memory is completely depleted, this error can stop the system. However, during the indexing process, if the amount of available nonpaged pool memory is very low, another kernel-mode driver requiring nonpaged pool memory can also trigger this error.
Resolving the Problem
To debug this problem: Use the .cxr (Display Context Record) command with Parameter 3, and then use the kb (Display Stack Trace) command.
To resolve a nonpaged pool memory depletion problem: Add new physical memory to the computer. This will increase the quantity of nonpaged pool memory available to the kernel.
