Blue Screen Stop 0x00000027 RDR_FILE_SYSTEM
Many people report on forums that they have encountered 0x00000027 RDR_FILE_SYSTEM error. Some of them report they encountered the blue screen stop 0x00000027 RDR_FILE_SYSTEM after cloning system on new HDD, some say they encountered this BSOD while loging on their computers, and some say they encountered it at work. In a word, this error occurs in various situations.
Then, what causes the RDR_FILE_SYSTEM error? The possible reasons are as follows:
1. The depletion of the nonpaged pool memory.
The nonpaged pool memory is related to physical RAM. If the nonpaged pool memory is completely depleted or if a kernel-mode driver requires the nonpaged pool memory while the amount of available nonpaged pool memory is very low, the RDR_FILE_SYSTEM error may occur.
2. Problems occurred in the SMB redirector file system.
Server Message Block (SMB) is a network transport protocol for file systems operations to enable a client (applications or end users) to access resources on a server. The SMB model consists of two entities: the client and the server.
On the client, applications perform system calls by requesting operations on remote files. These requests are handled by the redirector subsystem (rdbss.sys) and the SMB mini-redirector (mrxsmb.sys). Both them translate the requests into SMB protocol sessions and requests over TCP/IP.
On the server, SMB connections are accepted, and SMB requests are processed as local file system operations through NTFS and the local storage stack. The srv.sys driver handles legacy SMB traffic, and the srv2.sys driver handles SMB 2.0 traffic. The srvnet.sys component implements the interface between networking and the file server for both SMB protocols. File system metadata and content can be cached in memory via the system cache in the kernel (ntoskrnl.exe).
If these files related SMB are corrupt, the blue screen stop 0x00000027 will also occur.
3. Other corrupt drivers or system files.
As mentioned above, both rdbss.sys and mrxsmb.sys are drivers, which are system files related to SMB. Apart from these drivers, there are other drivers and system files that can cause the 0x00000027 RDR_FILE_SYSTEM error.
For example, the csc.sys whose description is Windows Client Side Caching Driver can also cause this BSOD. This file is also driver and you can find it under C:WindowsSystem32drivers.
4. Anti-virus software incompatibility.
Some users report that they encounter the RDR_FILE_SYSTEM BSOD because of mfehidk.sys. This file belongs to McAfee (an anti-virus software) and exists in the following two places: C: WindowsSystem32drivers, and C:Program FilesMcAfeeVirusScan Enterprise.
5. Infection of computer viruses.
The last possible reason is virus. Some viruses may disguise as system files and stop your system. You should make sure your computer is not infected by viruses.
