Bugcheck 0x27

I’m getting bugcheck 0x27 in my RDR2-based redirector. 0x27 is an
RDR-specific bugcheck, but I do not have any documentation on what the
arguments signify. The bug check is being thrown from RxFsdCommonDispatch
according to the stack trace. Does anyone know what information is
provided by the bugcheck or does anyone have any clue what would cause
RxFsdCommonDispatch to bugcheck?

Thanks again …

More info on problem …

The crash appears to occur in RxFlushFcbInSystemCache when called by
RxPurgeFcbInSystemCache. The exception record lists the address of the
FsContext (pointer to the FCB) within a FileObject structure as the
offending address. Note that the address listed is an offset into the
FileObject structure, not the address contained by that location.

Thanks for any insight. I’ve been stuck on this one for a while now.
