01172, 00000, "recovery of thread %s stuck at block %s of file %s"
// *Cause: Crash recovery or instance recovery could not apply a change to a
//         block because it was not the next change. This can happen if the
//         block was corrupted and then repaired during recovery.
// *Action: Do a RECOVER DATAFILE for the file containing the block. If this
//         does not resolve the problem then restore the file from a backup
//         and  recover it.
