C++ daemon: Unexpected error executing code for particular method, detected by Xmlrpc-c method registry code

Hi all,

I am developping a URCap based on a C++ daemon, communicating with a smart camera.
The URCap is working nicely but occasionally, I am getting the following exception popping up on my teach pendant:

Unexpected error executing code for particular method, detected by Xmlrpc-c method registry code. Method did not fail; rather, it did not complete at all.

It occurs, as far as I understood it, when the camera is sending back a rather long message to the URCap. As soon as I am transfering these data to the URCap with the xml-rpc interface, the exception is raised. It looks like that the data are well received on the daemon side.
I suspect either a timeout or a message length limitation, is there a way to increase these limits? I tried to increase the timeout in the xml-rpc client interface java class, without any success.

Any help would be appreciated. Thanks in advance.
