What does netstat say about client connections?
Does the server cleanup (remove) stale connections?
Thanks for answer.
1. Server's ram and cpu enough for ds server. There is enough resources.
2. i run "netstat -a" command and see clients. But i couldn't check in error status. is there any other commands to run and check?
3. No, Server doesn't clean up. How could i cleanup stale connections?

Hi,
i have a mobile app, using datasnap server.
Datasnap Server : A vcl standalone .exe program. Datasnap server (no rest), DBX and SQL Server connection.
Client : FMX app, Android clients and TClientDataSet.
A while before, I have 20-25 clients, there was no problem. But android client numbers increase, 190-200. Server running awhile but about one day later, it didn't response anything. Clients doesn't connect to server. I close and open datasnap server program. Then clients connect and operate again. How could i solve this?
object DSServer1: TDSServer Left = 96 Top = 11 end object DSTCPServerTransport1: TDSTCPServerTransport PoolSize = 250 Server = DSServer1 Filters = <> AuthenticationManager = DSAuthenticationManager1 Left = 96 Top = 73 end object DSAuthenticationManager1: TDSAuthenticationManager OnUserAuthenticate = DSAuthenticationManager1UserAuthenticate Roles = <> Left = 96 Top = 197 end object DSServerClass1: TDSServerClass OnGetClass = DSServerClass1GetClass Server = DSServer1 Left = 200 Top = 11 end
I increase Poolsize to 250. But it didn't solve problem.
Thanks.
