Dear All,
I’m working on a FS driver. The driver works fine on normal environment.
However, when Symantec Norton Antivirus installed, the system will
Crashes after running about 6 - 10 hours with a stop code:
0x0000007A (KERNEL_DATA_INPAGE_ERROR). The error status is c000009a.
I was told from !analyze -v: it means the request failed because a
file system failed to make forward progress.
Kb command indicated that my FS driver is not in stack.
My driver can work fine with out Symantec Norton Antivirus, and Symantec
Norton Antivirus can work fin with out my driver. But they can not work
Together. Of course, I know it is over 90% possible that the fault is on
My driver. However, my driver is not in stack when system crashes. How
to isolate the problem in my driver and what kind of problem can cause
this error?
Any info will be appreciated.
Thanks
It would be helpful to know what your driver’s purpose is. That might
give a clue as to why you’re having problems. Secondly, did you check
all thread stacks for your filter’s presence, or just the one that was
running at the time of the crash?

c000009a is STATUS_INSUFFECIENT_RESOURCES. I guess that some paging read
request failed because of insufficient resources that caused the bug check.
You need to find out what resource is exhausted, I suspect that it is
related to the memory.
As a first step in investigating the problem you can run !vm and !memusage
from WinDbg and analyze the output. It should provide you with some clues
where to look next.

It is a memory exhausted problem. I can see the memory usage is
increased as the system running. I searched the driver code and
found there many many memory allocations and deallocations in dispatch
routines. Is this possible that those memory allocations and
deallocations
generate fragmentation of paged pool which finally lead to memory
exhaustion
after some time of work? If so, how to prevent that? Using lookaside
list or
Something else?
Thanks

I don’t think that fragmentation can cause this. I would suggest you to type
in the debugger !vm and !memusage and look at the output. If it will show
that the paged pool is exhausted then type !poolused to see what tag is
associated with most of the allocated memory. It should give you a clue on
what is going on.
