I'm having an odd occurrence happen about 50% of the time right now when creating new web applications during my migration from SP2010 to SP2013.
During creating a web application in Central Admin, I can get through the first setup page, then get to the "This shouldn't take long" page and will sit there for 30+ minutes. I end up closing the window and will see that the Web application is there in Central admin, and sometimes the DB will be created, other times not, not a big issue since I'm mounting a sp2010 database to this web application.
What I do notice is that either a IIS site will either not be created at all, or it will be created, but the Virtual Folder is empty. When trying to delete the Web Application through central admin or PowerShell it will hang for hours until the next day when it's finally deleted. During this time I am not able to create any other web applications. It's usually at this time that I can successfully create a new web applications but even that is unreliable.
Has anyone ran into this issue or can suggest any workarounds to get this working? I'm wondering if copying the contents of another web application's virtual directory to the failed web application's virtual directory will be a workaround. I still need to verify if creating a web application through PowerShell gives me the same headache but at the moment I'm currently waiting for a web application to delete.
