Apache Ignite C#/.NET: Asynchronous Execution example failing -
facing different errors
Hello,
I tried to follow the Asynchronous Execution example
<https://ignite.apache.org/docs/latest/distributed-computing/distributed-computing#asynchronous-execution>
in the Apache Ignite docs, however I ran into some errors, and the errors
vary to the different implementations I have.
*Variation #1* I follow the example in the link above exactly - the
ServerNode
<http://apache-ignite-users.70518.x6.nabble.com/file/t3022/ServerNode.cs>
is run first then the ClientNode_1
<http://apache-ignite-users.70518.x6.nabble.com/file/t3022/ClientNode_1.cs>
.
From the server console, I see that the client connects
<http://apache-ignite-users.70518.x6.nabble.com/file/t3022/IgniteOutput_1.txt>
with the server, then the client immediately disconnects
<http://apache-ignite-users.70518.x6.nabble.com/file/t3022/IgniteOutput_2.txt>
. Finally, a whole slew of errors
<http://apache-ignite-users.70518.x6.nabble.com/file/t3022/IgniteOutput_3.txt>
follow.
*Variation #2* ServerNode remains the same - instead, I run ClientNode_2
<http://apache-ignite-users.70518.x6.nabble.com/file/t3022/ClientNode_2.cs>
.
In this variation, I run into these
<http://apache-ignite-users.70518.x6.nabble.com/file/t3022/IgniteOutput_4.txt>
errors.
I was wondering what causes these specific errors for these specific
variations and how I can resolve them - thank you!

Hi,
This is kind of expected, cause you don’t keep your client running.
Try adding something like Console.ReadLline() at the end of your client’s main
method.
When a task initiator lefts from the grid, there is no way to send the results
back, therefore depending on NODE_FAILED timing your either get:
#1 – “Topology projection is empty”
#2 – “Task cancelled due to stopping of the grid”

Hello,
I tried to follow the [Asynchronous Execution
example](https://ignite.apache.org/docs/latest/distributed-
computing/distributed-computing#asynchronous-execution) in the Apache Ignite
docs, however I ran into some errors, and the errors vary to the different
implementations I have.
**Variation #1** I follow the example in the link above exactly - the
[ServerNode](http://apache-ignite-
users.70518.x6.nabble.com/file/t3022/ServerNode.cs) is run first then the
[ClientNode_1](http://apache-ignite-

From the server console, I see that the client [connects](http://apache-
ignite-users.70518.x6.nabble.com/file/t3022/IgniteOutput_1.txt) with the
server, then the client immediately [disconnects](http://apache-ignite-
users.70518.x6.nabble.com/file/t3022/IgniteOutput_2.txt). Finally, a whole
[slew of errors](http://apache-ignite-
users.70518.x6.nabble.com/file/t3022/IgniteOutput_3.txt) follow.
**Variation #2** ServerNode remains the same - instead, I run
[ClientNode_2](http://apache-ignite-
users.70518.x6.nabble.com/file/t3022/ClientNode_2.cs).
In this variation, I run into [these](http://apache-ignite-
users.70518.x6.nabble.com/file/t3022/IgniteOutput_4.txt) errors.
I was wondering what causes these specific errors for these specific
variations and how I can resolve them - thank you!
