RESOLUTION
Because
other conditions can cause a Stop 0x0000007f error,
verify that the problem stems from a kernel stack overflow condition. To do this, obtain
a kernel memory dump file
from the computer.
In
order for this hotfix to work, you must also apply an update to NSI Software's Double-Take.
This update calls the
IoCreateFileSpecifyDeviceObjectHint
function.
This function gives a filter driver the option to stop recursively calling the NTFS
file system on the same stack. To obtain this update,
contact NSI,
and then
ask for hotfix HF28130.
The
stack space limit still exists in Microsoft
Windows XP and Microsoft
Windows Server 2003. However, the
IoCreateFileSpecifyDeviceObjectHint function is
in the kernel of
both of
these operating systems. If you
use filter drivers
to implement the function in these operating systems, you
can conserve
stack space.

822789
You receive a "Stop 0x0000007F"
error message or your computer unexpectedly restarts
If you implement the solution that
is described in Microsoft Knowledge Base article 822789,
the
Symantec AntiVirus Navap.sys
component
will check for a specified amount of free kernel stack space before the
component proceeds.
If the
amount of free kernel stack space is
less than that specified by
the KStackMinFree
registry value that
is described in Knowledge Base article 822789, the
Navap.sys component
will defer
its work.
If
you have already implemented the
solution
that is discussed in Knowledge Base article 822789,
and you
still
experience
kernel stack
overflow problems,
apply
this hotfix
with the NSI update.
If
you have implemented the solution and
have not experienced kernel
stack overflow problems
since then, you may want to apply this hotfix and then
reduce
the amount of kernel stack space that is specified by
the KStackMinFree
registry
value. In this scenario, the Navap.sys component
requires the lower amount of kernel stack space and may
be able to run more frequently.
