I am going to take the new web server down tonight for about 20 minutes to image the machine now that I have it stable and operating well.
There have been 0 owncloud errors and 0 php errors in the last 24 hours. This machine has never run this clean. Ubuntu definitely runs much better than CentOS.
An additional plus, it takes approximately three seconds for a reboot as opposed to close to two minutes under CentOS.
