Gentlemen, our production site is full of the following errors happening very regularly at around an hour's interval. I have looked web like anything to find the solution but did not find any. The major problem is when this happens, no one can log into the site, site behaves way weared and gets into a kind of locked out state. We cannot do anything but to wait and see when we can log back in. These errors always come in group of three.
This is happening live at my production ecomm site. Extremely consistent since the day I implemented dotnetnuke, but now has gone to critical stage that I need to fix it.
Someone please help, anything for any assistance/guidance.
