Hi, until now, the maximum number of this type of error was 7 / 8 in about an hour with a maximum of 700 user about how to peak, usually with 500 user, you will get about 4 / 5 errors in a 'hours. But then depends on short, the only thing I've noticed that in general, if the error comes out all the time usually 2 / 3 times in a row, then makes like a pause for the next hour ... then maybe it does more ... Or sometimes repeats itself ...
I hope I was clear with my own additional information, I thank you for your support and for the excellent work you are doing. Keep up to early and good start to the week ;-)
