Hello Sanjay,

8.5 what version exactly?
Just asking as some 8.5 I´ve seen have more cut-offs than normal. And when the client cut-offs and if you don't have the reconnect option on as automatic, this can happen.
One other occurrence is with concurrent users. The main thing here is that the network between server and client might not be stable, or it can be but the client interprets it as not
