I'm serving CakePHP 3.x based sites off a Network Load Balanced (NLB) IIS 10 cluster. The php files reside on an external DFS share. When run with debug enabled, CakePHP throws the following error:
2017-08-16 13:45:39 Error: Fixture creation for "requests" failed "SQLSTATE[HY000]: General error: 10 disk I/O error"

IIS has full write permission to the project root folder (on the network share). The fact that CakePHP error log has captured the above info. proves it. So this is definitely not about file / folder permissions.
What's could be the cause of this error and how to fix?
Thank you.
