Symptom

The following is error is thrown in the Designer's Console, after executing a Process or a Mapping from the Designer:

Exception : java.rmi.UnmarshalException: Error unmarshaling return header;
nested exception is: java.net.SocketTimeoutException: Read timed out

The Process or Mapping is however executed, despite this error.

Most of the time it appears when executing a big Process (with a lot of sub-processes for example). 

 

Solution

This happens on environments where the connection between the Designer and Runtime is slow, causing this error.

There is an option in the Designer allowing to increase the timeout for the communications with the Runtime.

You can find it under Window > Preferences > Stambia > Runtime > Runtime Timeout (milliseconds)

 Preferences

You can increase this value until the error disappear.

Note:

Set it to '0' for an infinite timeout.

We advise to use this only for testing purposes as it is better to find the right timeout corresponding to your environment.
