How to solve System in under Maintenance

If you face this problem when fill up application or make temp file... My suggest Please complete your fill up application or make temp file within from 12:00 pm to 5:00 pm.

Because... maximum applicant fill up or make temp file in this time 6:00 pm to 10:00 am. but website can allow 1400 applicant at a time, that at a time 4500-6000 applicant fill up or make temp their application. so in this reason maximum applicant face this problem.
