4) See lucene index errors such as:

"An exception occurred on the server while executing UI/Data/Search/Search: IndexFormatTooOldException: Format version is not supported (resource BufferedChecksumIndexInput(SimpleFSIndexInput(path="/[sharedfs]/lucene/Page/segments_48"))): 1 (needs to be between 4 and 6).
