Additional Information

we receive communication error, I/O error on nim session while removing device from maintenance schedule for several reason.
1. due to less timeout setting at USM,also due to more data on maintenance_window table.
2. default setting for  /setup/purge_maintenance_windows is set to 24. we recommend to set to small value to 1 which reduce time significantly in maintenance_mode.cfg.
