TCP Inbound Gateway with Splitter/Aggregator multi-threaded.

[Gary Russell]

Interesting; at timeline 2011-05-10 09:25:55,312, we can see the message being bridged from the configured reply channel to temporary channel that the tcp thread is (should be) waiting on, but for some reason it's not picked up.

The next reply (at timeline 2011-05-10 09:26:54,230) is sent ok.

Can you reproduce with the thread name in the log (%t) and, after a failure, get a thread dump (jstack <pid> on *nix, Ctrl-Break on windows - or use VisualVM) after a failure?

I will attempt to reproduce, but I won't be able to get to it until tonight.

Thanks

Here is a log with the thread info in it.
I've also added the thread dump.

I know it has to do with loosing the link to the initial thread or something like that.
If you need anything else let me know.

Here's the smoking gun...

The gateway is timing out after 1 second and your reply is taking 2.6 seconds.

The default timeout for a gateway is 1 second; this can be increased by using the reply-timeout attribute on the inbound gateway.

As you have seen, this won't happen on a single thread, obviously, because the thread is doing work rather than waiting for a response.

Hope that helps.

X-File Classified.
I've set the timeout to 60000 (millis) and boum, it all started to work as a charm.
If you want Gary, as a sign of my gratitude for your help, I'll simplify a bit my workflow and think of some sort of nice funny project (Cafe Sample V2?) and give it to Spring Community.
A sample of a TCP client/server with multi-threaded processing per request. You'll be able to put a link from here to the sample.
Would that be of any used?

Best regards,

That would be great!

You might want to consider getting an account on git.springsource.org.

The samples are here ...

http://git.springsource.org/+spring-...ration/samples

You could then make a clone up there and push your changes, and then send a merge request to Mark and Oleg.

We really would like to see folks contributing to the samples; thanks for the offer!

BTW, I have raised a documentation JIRA issue, because I didn't see this default documented.
