When sending a map broker to production, the error message appears :
(Broadcast) 1 - 102 - Commit failed (client-side): < Error unmarshaling return header; nested exception is:
(Broadcast) 1 - java.io.EOFException>

The XML is to big to send to production, so the timeout of broadcast agent defined by default at 60 is to short.
This timeout can be increased to 600 or more with adding the line :
xib.cfgserver.timeout=600

in the following file :
Synchrony_V4.0\Integrator_V3.3.1\local\broadcastagent\agent.properties
