Oracle Linux 6 and 7 virtual machines experience hangs, as when running the ps command, with processes becoming stuck in D state.

The VMs experiencing this issue are running on a VMWare ESX host, and have been installed with a kickstart template and OL 6 and OL 7 install isos.

The following is seen when checking the process id of one of the hung processes:

$ cat /proc/17394/wchan
