0xC0000005 Access Violation

[ChrisSp]

Hi all,

I realize there are quite a few threads with a similar Crash report and I believe I have read them all, but I hope someone can help me out here.

In this particulair program I customized some GUI stuff, mainly gauges and a couple of static bitmaps on the background, but for some reason it keeps crashing with a 0xC0000005 Access Violation. The Exception is at EIP 0x07E504A3. The program runs on a server computer to which 4 tablets (that run Windows 8.1) connect using an application reference. This setup proved very stable in various projects and hardly ever changes.

The problem is that the server pc (running Windows 7 pro, admin user) crashes about once every day with this report.

One thing that has helped me in the past is the binary search method.  Disable large parts of your application and see how the crash behaves.  Does it go away when you disable report generation?  Does it go away if you disable the customized GUI stuff?  What about any specialized .NET or DLL calls?  It is time consuming most of my major crashes have been found this way.

Also checkout memory usage.  Windows 7 comes with a Performance Monitor that lets you log memory usage and CPU usage on an application over time.  There is also the execution trace toolkit that might help if again this is a memory related crash.

Hi Hoovahh,

Unfortunately the customer relies on the application and has to deal with resetting the pc once a day. However, they are located in a different country and I do not have access to the computer. They monitored the Memory and CPU consumption for the first hour, without any increase.

Like I said, the program runs fine on my pc, no memory leaks, handle increases etc. I already eliminated all DLL, .NET and ActiveX calls.
