This is a very open ended question and I am really just looking for how to approach locating the issue.

The application runs for a day or so and then will crash while being used. The point in the application that it crashes is not the same each time. The memory that the application is using is not increasing.

C++ is not my standard dev language so any pointers would be appreciated.

The run time error I am given is detailed below. Having googled this I can see that 40000015 is a generic I don't know what has happened style error. Is there anyway I can use the additional information (1-4) to assist in locating the issue?

Any help is much appreciated!

Thanks

  • Did you try debugging or inserting logging statements ? Do you generate a log file ? Pour over the log and search for patterns in the log when the crash happens. – DumbCoder Apr 03 '14 at 09:08

I would start by running it under debugger and leave it running for a day. Remember to enable all exceptions to catch - in my VS 2005 its in Debug->Exceptions, add handler for 40000015 exception.

If you cannot run it under debugger, ie. it happens only on client PC (still you can use remote debugging), then you can implement exception hanlder using : AddVectoredExceptionHandler, then use StackWalk64 to log call stack. If you can compile with symbols, then such stack will contain full path to the source of exception. It will be inside MSVCR90.dll, but will originate probably somewhere in your code. If you cannot include symbols then you can always use .map files or windbg with locally stored .pdb files. Of course this is a lot of work especially if C++ is not your main language, so the first suggestion is the best for you.

Ok, you can also use MiniDumpWriteDump and then use windbg instead of StackWalk64.
