   errors from the I/O subsystem.  I/O error entries will be lost
   until the cause of the excessive I/O logging is corrected.
   If the diaglogd daemon is not active, use the Daemon Startup command
   in stm to start it.
   If the diaglogd daemon is active, use the logtool utility in stm
   to determine which I/O subsystem is logging excessive errors.
