Any more thought s or suggestions on this issue?
I have been plagued with this issue ever since I upgraded to 11.1. I thought the U4 upgrade was the cure but my system still reboots almost daily.
My system is a Dell Poweredge 2950 server with the root drive being an SSD.
My log messages doesn't show a lot of items worth noting but I have included it just for grins and giggles.
Any thoughts?
