I am responsible for the data processing and analysis for two identical spacecraft for a NASA science mission. I am running one SQL instance for the first spacecraft on a Windows 7 machine and another instance for the second spacecraft on a Windows 8 machine. Both installations were done the same and both have been configured with the same scripts and use the same login credentials.
The issue that I am having is that the SQL Server on the Windows 8 machine randomly fails and shutsdown when I am submitting a large amount of data into the database tables. When I do this exact same operation on the Windows 7 machine I have never had any issues. This of course causes a significant amount of issues in regards to overall data processing since there are up to three difference processing systems working with each of the SQL Instances.
I am not a SQL DBA nor have significant training in SQL but have used it for a decade or so and write a significant amount of C# code interfacing with the system. As a note, the code that I'm currently using interfaces with the SQL servers via LINQ.
Does anyone have any thoughts on what might cause the issue for the Windows 8 machine and not for the Windows 7 machine?
I would greatly appreciate your help.
In the meantime I've written a small service that looks at the system every minute and if it is shutdown it restarts the service but this is NOT an optimal solution.
