Since there can neither be a chunk #4095 nor a page number 1048575 (0x000FFFFF) which would be in chunk #0 (zero) I assume the root chunk has been corrupted somehow so that the chunk table was damaged. Time to check that you are not seeing a hardware problem (check the system logs) and then get out the backup tapes. I see the thread was an ontape thread. Were you doing a restore? Perhaps from a tape made on another machine? If so make sure the chunk links are all available and pointing to files or devices that are large enough to hold the data you are restoring. Art S.
