Hello,
I have been going through the process of creating an enterprise geodatabase, staging utility network, applying asset package, and then publishing a feature service to our Portal.
I have done this process numerous times before. Unfortunately, I am running into an error when trying to run the geoprocessing tool "Enable Network Topology".

I am using SQL Server to host the enterprise geodatabase. At first we thought it was a resource problem so we scaled up the database and VM used to publish the feature services. Unfortunately, that did not resolve the problem. This customer-supplied asset package is the biggest I have ever worked with before containing over 20 million features in their electric utility network. The geoprocess hangs at 2% and then fails like clockwork around 1 1/2 hours.
I've tried to also run this process on my personal computer in the past in which I received a different set of errors after the process ran for 8 1/2 hours.

This set of errors could be caused being I'm using my personal computer on not the most stable of networks. However, I would get the same set of errors around the 8 1/2 hour mark on each attempt.
I then went back to the VM we used for publishing as it is hosted at the same data center as our database. This is where I'm stuck with the "General Function Failure" error message that gives me no insight as to what is wrong. Any insight is greatly appreciated!
