SYMPTOMS
While in the phase where Dumpchk.exe validates all virtual addresses, the
program reports that specific memory dump files are corrupt. These same
memory dump files are not corrupt and may be debugged without any problems.
CAUSE
Dumpchk.exe does not correctly handle a situation where there are "large
pages" in the memory dump file. This leads the program to incorrectly
conclude that memory dump files with large pages are corrupt.
RESOLUTION
Obtain the hotfix mentioned below.
MORE INFORMATION
Memory dump files are generated when a system STOP error occurs provided
the system has been correctly configured to save debug information through
the Control Panel.
These memory dump files can often be used to diagnose the cause of the
system STOP error. Because these files are often very large, Dumpchk.exe is
often used to determine whether a given dump file was generated
successfully or whether it might be corrupt and therefore not useful. The
problem described here can result in some files being rejected when they
are not corrupt.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0.
This problem was corrected in the latest Microsoft Windows NT 4.0 U.S.
