In Windows 2008, it causes frequent crash of windows resulting in blue screen. On debugging the crash dump file, it shows VISTA_DRIVER_FAULT and points to a process that belongs to our application. On collecting crash dump two times, it showed two different processes that belong to our application. From the stack trace, I am unable to get much information other than some kernel related symbols. How do I proceed to check what is the cause of the problem from the crash dump? The following is the output of the stack trace. The process NodeScann in the trace belongs to our application. How do I use the dump to find out exact cause of the dump. I tried loading all the pdb files of our application etc, but unable to get any info from the stack trace.' Any help or pointers in finding the causes of this blue screen problem is highly appreciated.

Bug Check Code 0xF4: http://msdn.microsoft.com/en-us/library/ff560372(VS.85).aspx The process NodeScann is the cause of the BSOD. I think it belongs to Node antivirus. Do you have it installed? If yes, check with Node Technical Support. This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

The process is not an anti virus. It belongs to our application, which internally users ssh application putty to scan linux/ssh nodes. We are not using anything that can cause the OS to crash. How do we check what is the cause of the problem? Can this happen due to Putty executables that we use? Thanks Prakash

What I can extract from the dump output is that this application is the cause of your problem. You have to contact your vendor Technical Support for more information. If there is an update of this application then install it and check again. You can also contact Microsoft CSS.
