Hi All,

Is there any chance for global variables getting corrupted in a legacy file
system filter driver.

When analysing a crash dump I see that one of my list entry which is a
global variable is corrupted, it’s Filnk and Blink say memmory access error.

any information would be helpful.

thanks,
Kedar.

How are you synchronizing access to that global? If you have no method to
serialize access to that global then most likely that is the explanation.
Classic example is that code working for millennia on a UP and then
failing the first time it is run in a multiprocessor environment.
