Control Board - SCUA Version：MA5600V800R003C02B108SP001.
MA5600T MSAN maincontroller-board, SCUA, saved software process of database overrun 7 minutes.
We have followed these steps on maincontroller board:
2.active configuration (need to reboot system)
3.save configuration once more after system rebooted to check the problem is solved.
This problem was generated by the unused space in the VPR configuration table of maincontroller board's database. It hadn’t been initialed, which will induce system have to read some random value and spend a long time during compression-phase.
