You can expect getting 1017 errors here and there when a server is very packed and a lot of people are trying to log in at the same time. I don't know what the Queue max number is but I would assume if you are not getting it then it's at max capacity. I know people are going to be pissed when I say this but obviously SE has done something right. Instead of 100k people getting a 1017 error and posting on the forums a limited few are and since restrictions are still in place on servers it would seem everything is working as intended at the moment.
