Thank you Mr. Martin. Your suggestion did works in one situation that appeared to me here in this time. 
All right!
But, I have another question, how can I solve the situation on the attached screenshot?
I don’t know why, on my UM I have two connections with pending events. Neither of these connections are triggers and the triggers aren’t acknowleding the 12 Events that are in queue.
I tried to find the Connection ID on the channel Connection tab but there is nothing there, just a empty list.
The “Total Events” are just growing and for some reason the application doesn’t processes the message.
Please, what should I do? I just need to get these events to be sent to the trigger and processed, but until now I couldn’t.
It’s giving me headaches and I didn’t find anything about in Documentation
