Connection reset alerts.

Hi,

We are receiving many connection reset alerts for one interface everyday. Its an SFTP Channel and to avoid the alerts I have kept it under schedule for an hour(from 8pm to 9pm). In that one hour itself I am receiving almost 200 alerts, But there is no failure, we are receiving the file successfully. Here I have 2 questions, Please help me in understanding:

1. How to minimize the connection reset alerts

2. I see alerts are generated even after the schedule time. means i saw the alerts are received till 11:30 pm,but the schedule is till 9pm.

Thanks,

Vijay
