Starting from saturday my application receive a notification every 5 minutes for items sold, of course, once.
I checked the apache log and there is no error logged, that means that the programs ends correctly.
I did not made any change to the application and everything worked fine till saturday.

Someone did something but the issue is still there!

At this pace the problem will be solved in 2117.
