Connection Reset By Peer (Timeout?)

Hello, 

I have a multi-tier application using datasnap (WebBroker Application) on IIS.

It's working fine, but sometime, when the user doesn't work a lot with the application I got a 'Connection Reset By Peer'
(about 3 minutes)

I guess, there is a timeout somewhere... Is there something special to configure on the IIS Application Pool?

Thank you,

Eric

Hi Eric,

Have you tried setting the SessionTimeout property of the DSHTTPWebDispatcher to 0? This will disable the property,

Hi Vlad,

I'm still in Delphi 2010 and there is no SessionTimeOut property on TDSHTTPWebDispatcher... Or I'm missing something?

Thank you,

Eric

Hi!

Any other idea?

Hi Eric,

IIS Application Pools contain some worker process recycling options like terminate after idle time.  Try disabling these.

I did...

Recycling conditions are all disabled...

I also checked the advanced settings  to disable limits (as a test)

The Connection Reset by peer is catched in the reconcile error property of the clientdataset... (which I found also strange)

Firemonkey Datasnap client connection reset by peer or socket error

Peer to peer connection
Hi, I'm trying to make a program to transfer files between my pc and another that is behind a router. My side will act as master and the other just as a slave, serving what master asks without user interference. I know that the easiest way is to run a idTCPserver at the slave side and a idTCPclient at master's side, but this needs to forward the used port at the router. I want to keep out of this. So I try the reverse way. A idTCPclient at slave side and idTCPserver at my side as master (in my side I can forward ports). Starting the slave it connects to master-server. Af...

sqlconnection datasnap connect timeout
Hi. On the client I set up an connection to the server TsqlConnection --> Driver = datasnap But setting the ConnectTimeout property does not affect how long the client tries to establish an connection to the server I use http protocol Anyone that has an workaround? I know what should be done, but not quite how I can do it. After some debug I see that the SQLConnection uses TDBXConnectionFactory to create a new DBXConnection. TIdTCPClientCustom.Connect will eventually be called. (IdTCPClient.pas) IOHandler.Port := FPort; //BGO: just to make sure IOHandler.Host := FHost; IOHandler.ConnectTimeout := FConnectTimeout; IOHandler.ReadTimeout := FReadTimeout; when these lines are reached Port and Host are the same as the properties set on the TSQLConnection at design time. But ConnectTimeout still is the default value 0. Not the value set on the property "ConnectTimeout" set on the TSQLConnection. If I could set the IOHandler.ConnectTimeout to a value of my choice. Problem solved. E.g IOHandler.ConnectTimeout := 5000; Means that if the server is down the client tries to connect for 5 seconds before an exception is thrown.

#10054 Connection reset by peer
Hi, I upgraded from Indy 10 r3830 to r4103. Now I (very) often get this #10054 exception after I disconnect. The same application using r3830 doesn't have this problem. In the status event of IdFtp: Disconnecting then Disconnected but then this exception (#100054). I found some changes in IdFtp "DisconnectNotifyPeer": - r4103: procedure TIdFTP.DisconnectNotifyPeer; begin if IOHandler.Connected then begin IOHandler.WriteLn('QUIT'); {do not localize} IOHandler.CheckForDataOnSource(100); if not IOHandler.InputBufferIsEmpty then begin GetInternalResponse; end; end; end; - r3830: procedure TIdFTP.DisconnectNotifyPeer; begin if IOHandler.Connected then begin IOHandler.WriteLn('QUIT'); {do not localize} end; if IOHandler.Connected then begin if IOHandler.Readable(10) then begin GetInternalResponse; end; end; end; I changed IOHandler.CheckForDataOnSource(100) to IOHandler.CheckForDataOnSource(10) in r4103 and now there are no #100054 exception message anymore.

ISAPIDLL and "connection reset by peer"

There are no login/beforeconnect/disconnect events fired on Tsqlconnection ( client ), keepconnection can be true or false without any difference in behavior, so .... what's wrong and how can I solve this ?

Using IdHTTP I get Error 10054 Connection Reset by Peer
Hi, I'm trying to get a GIF image from a website every 15 minutes. But it only works the first time. At the next attempt (after 15 minutes) I get the error message. Here is the code : procedure TForm.Timer1Timer(Sender: TObject); begin GetRadarImage; end; procedure TForm.GetRadarImage; var MS : TMemoryStream; GIf: TGIFImage; begin MS := TMemoryStream.Create; GIf := TGIFImage.Create; try IdHTTP1.get(RadarURL,MS); Ms.Seek(0,soFromBeginning); Gif.LoadFromStream(MS); Gif.SaveToFile(ExtractFilePath(ParamStr(0))+'radar.tmp'); finally FreeAndNil(GIF); FreeAndNil(MS); end; end; I'm doing something similar on another website to get XML data, and there it works fine. The only difference between the two http calls is the overloaded method. In this case I'm using the procedure procedure Get(AURL: string,AResponseContent: TIdStream); overload; // this one gives the eror while in the other case I'm using function Get(AURL: string): string; overload; // this one works fine Should I reset something before calling GET again ?

Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
What does this error message imply? .... i guess it does imply that you are not closing your connections. And/Or, you are not coding correctly to enforce Connection Pooling. That means you are not using the same connection string each time. To do this, create an <appsetting> in your WEB.CONFIG that is your connection string and reference it in your code any time you need to connect to the database. And as Moon pointed out, close your connection as soon as possible. Take a look at Connection Pooling Hi all, I want to raise this issue again in this forum with hope to get correct a...
