I am using evaluation license and using single connection server. I am doing benchmarks, but when the number of sessions crosses 600, view disconnects existing sessions to allow new sessions. The below error observed in view logs. I tired with ssh tunneling on/off, but same issue. The resource utilization on view connection server seems to be OK.
