I do and I regard them as a bug in need of refactoring. I just ran sloccount on one of our key services and the largest non-test file is 106 lines. It has three methods that do not call each other. The largest test file is 268 lines.

Then again we have another service with four files over 1000 lines (1441 the biggest), and we experience significant pain: not because of the size of the files but because of what the size of the class means about its design. That's on a team that had significant pressure to meet some tight deadlines. They are now actively working on refactoring those classes - again, not because of the size, but because of the design.
