WebService Socket Timeout Exception before reaching timeout duration

Question

Hi
My Server is Websphere Application Server 6.0.2.17
i got some times socket timeout exception before reach timeout duration. and also i have only default websphere settings for web service .
The exception is occurred in 19 seconds after hitting the service . i am not able to get the exact problem . because default timeout time is 300 seconds (i think like that)

Hi Mark,
with synchronous messages it is important to consider timeouts from each connection to be established. So soapUI-PI, then PI-BackendSystem plus anything that might be in between. If your timeout soapUI-PI is smaller than the following ones, you'll get that phenomenon. soapUI will cut the connection, but PI will hold it and maybe receive an answer from the backend. This answer will end up in the void, since the original requester (your soapUI) has already disconnected. But for PI, this will be OK and status "successful". PI does not control and monitor the client's connection.
In other words, the cancel of the connection is only performed for that same connection, it is not propagated to any subsequent connections.
Hope that I was clear enough,
Jörg
