Hi SaiPrasadReddyY,

I checked your project and Ideed I found some differences in these dependencies:

CookieManager 2.0.0
Microsoft.AspNetCore.Http.Features 2.0.0...

Hi Tomas,

Yes, the "Current delay" messages are printed in the same log file (unless special customizations), so we can assume that your Lightstreamer is not suffering from generalized delays due...

Hi Tomas,

Yes I can confirm that this kind of error may be due to slowdowns in the execution of client requests.
In particular this specific error means that a subscribe request from a client was...

This issue is not very clear to me.
Do you mean that some Items subscribed in COMMAND mode, once they are no longer updated from the back-end, also disappear in the client view? This would be...

Hi rvkvino,

I have just taken a quick review of your code, and indeed I cannot provide a definitive answer but some tips to continue the investigation.
I think you should start by monitoring...

Indeed, in this case I would start the investigation from the initialization operations performed in the Adapters, since they seem to fix the issue.

Maybe you have a forever loop that once...

As you can see from the log, the messages reporting received updates from the Data Adapter ("INCOMING DATA for ... ") disappear completely from 03:50:01,925; but the rest of the server activity...

Hi rperseguini,

Ok. Just a consideration about something unusual we found in the http headers:

Content-Encoding: Chunked

"Chunked" is something unexpected, maybe is not related to the issue,...

Hi rperseguini,

I can confirm that the server log would be very helpful as it can confirm whether the create session request is correctly processed and the respective response sent back.
In that...

Hi rperseguini,

Usually in this kind of issue the cause is to be found in some network intermediary that blocks or buffers the answers, preventing the correct reception by the client.
Are you...

So, with subscriptions loggers at DEBUG level you should be able to follow the entire flow relating to each Item, starting from the subscription request to the adapter and all the updates received by...

Unfortunately, the client error you mentioned (LS_cause=new.timeout.5 .2.error) is not enough to figure out what is going on.
Indeed, the error means that the client was unable to create the session...

Your code looks absolutely correct to me.
I just made a couple of minor changes:



var myClient1 = connect("http://localhost:8080","WELCOME");
var myClient2 = connect("http://localhost:8080",...

Hi sdi0900,

I am not sure if that could be a server-side issue or related to the client.
But just to avoid misunderstanding please take a look at this example changed to get the same real-time...

Hi ManKeer,

Yes, if you don't use a build tool such as Maven, Gradle or similar, you need to gather the necessary jars yourself by going up the chain of declared dependencies starting from the...

Hi ManKeer,

Please add to your project also this dependency:

<dependency>
<groupId>com.lightstreamer</groupId>
<artifactId>java-system-out-log</artifactId>
...

Hi ManKeer,

Are you targeting a local server or our public demo server?
Please double check the args[0] argument passed when you launch your code.

Giuseppe

You need to add also this dependency to your project: com.lightstreamer:ls-log-adapter-java:1.0.2 (https://mvnrepository.com/artifact/com.lightstreamer/ls-log-adapter-java/1.0.2).
If you use a...

Each Lightstreamer client session is reserved for a "host/Adapter Set" pair.
So if you need to connect your client application to two different hosts you need also two different client sessions, ie....

Hi,

This is strange, because the browser console reports a regular client polling session, and indeed you can see some data received, such as:

d(2,1,'5066 9','50687',6)

and

d(2,4,'24.4...

Hi,

The javascript you showed is the normal reply to a create session request from the client, so it seems ok from that side, and gives us no clue on the actual cause of the issue.
You should...

Hi ManKeer,

There are internal queues in the Server that could accumulate delays for outgoing updates, but there is no different treat for the various clients.
The queues compensate for clients...

Hi mojtabamn,

Please could you expand a bit more about the scenario of your application; for example you are targeting a local server or the Lightstreamer demo server?
Do the delays seem constant...

Hi Chuck,

Are you referring to this project https://github.com/Lightstreamer/Lightstreamer-example-Quickstart-client-dotnet/tree/for_version_4?
In this case I have no evidence of the compile...

Hi Kay,
