Actually, NAV should never crash, but sometimes there are circumstances that cause a crash of one of the NAV processes or services. For the user and the administrator, it is usually not clear why a component crashes. Most of the time the application event log does not show enough information to determine root causes of the crash.
A "crash dump" provides very good information about the module and code which caused the crash. The crash dumps can be analyzed by Microsoft Dynamics NAV support and help a lot to find the problem.
With the "Debug Diagnostic Tool v1.1. 2" it is very easy to create the crash dump files in case of a crash.
The tool can be downloaded under the following link: http://www.microsoft.com/en-us/download/details.aspx?id=26798
Note: If the operating system is not configured for "en-us" for region and language, then the following steps are necessary to install the Debug DiagnosticTool v1.2:
After you install and run the application, you are welcomed by the "Rule Wizard."
For the crash dump creation, you choose Crash and then choose the Next button. Following is the selection of what you would like to check. For NAV, it is necessary to select "a specific process":
The next selection window shows all processes. Here, you can select, for example, "Microsoft.Dynamics.NAV.Client.exe".
With "Advanced Configuration" it now possible to set the granularity of process monitoring.
The next screen shows the path where the crash dump is saved. You must select a hard disk with enough capacity. Crash dumps can be very large in some circumstances (e.g. if you selected "Full Userdump" in the "Advanced Configuration" screen).
In a last step the rule must be activated:
Once the created rule was activated, "Debug Diag" monitors the configured process.
In case of a crash, "Debug Diag" creates now the necessary .dmp files in the specified folder and additional log files in the installation folder of "Debug Diag" (e.g. "C:\Program Files\DebugDiag\Logs").
I hope the described steps help you to create the important crash dump information.
