I think this is a valid gripe for people who are less familiar with the genre and scope of most epic fantasy books. Lots and lots of characters of varying importance to the story (do I really have to remember the second maidservant's name...?) and, since this is fantasy, some incredibly weird names (Blödhgarm...author, are you yankin my crank?).
I'm not a fan of the crazy weird name thing, so hopefully that'll appeal to readers who see an umlaut and throw the book in the firepläce. But I'll confess, I do have a lot of characters. The world is populated by lots of people because, well, it's a world. I did resist the urge to name every single guardsman or street merchant who walked by, but I operate from the basic belief that everyone has an interesting story to tell (both in the world of my books and in the real world), even if those stories don't get to be told just then.
So how to keep things organized in the reader's mind? Well, I try not to throw too many names out there at once, and I do my best to establish a consistent context for them based on the current POV character's perspective. For example, one of the heroines of The Queenschair, Arsaya, has a rather unkind way of looking at the people around her, and presumably her thoughts about them (and her nicknames for them) make them a little easier to remember.
In Arsaya's mind:
Yennava = "Mama who doesn't appreciate me much"
Garland = "Papa who doesn't appreciate me either but at least he spoils me"
Zeydric = obnoxious big brother, "Beautiful Boy whom Mama loves more than she loves me"
Ebreyon = the great and magnificent King (heavy sarcasm), "Smiley"
Selana = the beautiful and graceful Princess (even heavier sarcasm), "Devil Eyes"
And so on and so forth. As long as the characters aren't presented as lifeless names on the page and have proper stories/attributes/roles attached to them, I think they stand a good chance of "living" for the reader.
But for those who just can't keep track of all those names, an alphabetical list of names and characteristics always helps! Mine appears at the back of the book but is carefully designed not to contain any spoilers from the book itself, so it's safe to check while reading. Or right here:
