[SOLVED]Receive MTOM attachment sometimes hangs

Well, I wrote a standalone client application to use instead of soapui and the MTOM attachment is delivered just fine. No hanging, no 100% CPU usage.

If I use soapui with the exact same request details and exact same endpoint, I get the hang and 100% CPU usage I described above.

Presumably there's something up with soapui's MTOM handling.

Hi!

Definitely.. are you using the latest version? I'll have to think of some way to reproduce.. I'll let you know..

sorry for the inconvenience..

I'm using 3.0.1 community edition on both Linux and Windows.

I can try and zip up a minimal complete Eclipse workspace and send it to you if that will help.

The problem with using Spring-WS is that there tend to be a lot of dependent jar files and that might make the zip quite big.

Here's a thread-dump on Linux when soapui hangs on a large attachment, maybe it's of some use to you...

Here's a bit more info for you.

It seems soapui does not actually hang, rather it is very busy for about twenty minutes while processing the response.

The sequence goes like this...

1. Invoke web service
2. http log shows the received message in full.
3. Progress indicator in the response window animates for a while, but stops after a minute or so.
4. User interface is almost totally non-responsive, OS "top" tool shows the soapui process at >100% CPU.
5. Approximately ten minutes later you hear the 'beep' when the response gets validated
6. User interface is still non-responsive, CPU still shown at >100% CPU.
7. Approximately ten minutes later everything finally comes back to life and the UI is responsive again.
8. soapui request window reports "response time 509ms (4517520 bytes)"
9. The attachment is available in the "Attachments" tab, and is byte-for-byte perfectly received.

As stated earlier, if I don't use MTOM and instead in-line the attachment, everything works very nicely and quickly.

Here is what I get if I do "Help -> About" inside soapui: Build soapui-3.0-dist-24-2009-08-09, Build Date 2009/08/09 19:52
The title bar of the application states "soapUI 3.0.1".

Hi,

thanks for all your detailed info, I'm going to dig into this now.. lets see what I find :-)

Hi again,

Just to check; which soapUI version and JRE version are you using?

Can you attach the WSDL for the service so I can try to mock it inside soapUI ?

Server is Tomcat 6.0 running on JDK 1.6.0_14.
SoapUI runs on JDK 1.6.0_14.
SOAP version 1.1.
Spring-WS 1.5.8.

It's not a perfect schema since I'm just testing/experimenting at the moment. I used Eclipse's web tools to generate the schema part, and Spring-WS auto-generates the WSDL for that schema.

The response doesn't validate against the schema when using mtom because of the include element that gets generated for the mtom attachment.

Hi!

thanks.. hm.. do you mean that the XOP Include is visible in the response XML? What about the attachment, is this only visible in the response attachments tab or in the message also?

regards!
