I can think of something going wrong in the OS, may be. Here is the OS version story:
I bought Windows 8 Pro. That got a free update of 8.1. Then I installed VMWare for virtualization and was running a CentOS on a VM. Then I got Windows 10 update, sometime during that update it warned me that VMWare might not work correctly after update. I ignored that. Later I realized VMWare is actually getting terminated with some error. My idea was to run the CB on CentOS VM. But then I thought I can directly run it on Windows. So I installed and was facing these issues. I felt Windows 10 is killing it. So I thought of formatting the OS. But I gave it one more chance and thought of resetting the OS to factory defaults. I decided if that also fails I will go back to Windows 8.1, because Oracle VirtualBox was not so comfortable. But after reset it worked.
I will try installing it on Azure IaaS. Should I use A3 or D3 machine on Azure ?
