Hey Shawn, I added segments file information (name and size) to Core admin status API. Turns out that you might get into NoSuchFileException if indexing happens and the commit point has changed, but the IndexReader LukeRequestHandler receives hasn't picked up the new commit yet, in which case the old segments_N file was deleted and computing its size resulted in that exception.
I pushed a fix for it which will be released in any one of future releases, including 5.5.1 if we'll have any. The fix includes logging the exception and returning -1 as the file size.
