SYMPTOMS
Under heavy file I/O a computer running Windows NT may blue screen with The following Stop error in CcFastCopyWrite.

Stop 0x0000000A (0xC8663000, 0x00000002, 0x00000001, 0x80101A6C)



CAUSE
When an application writes data to the middle of a file, Cache Manager does not check this case properly against a write beyond the end of the file. For this to happen both the end of the file and the current write location need to be in the cache plus there needs to be a special layout of cache memory.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
