I found the problem on a roll of T-Max 400 I developed, then came on here to research it. Thanks to the info in this thread, I found that I had two boxes that fell within the problem batch numbers. I emailed KodakAlaris last Thursday with a sample image showing the problem, as well as photos of the boxes with the batch numbers. Mr. Mooney replied within two days and shipped replacement film that arrives tomorrow. That's pretty great service in my book.
