Hi,
This is regarding the sample 53 for the esb 4.8.1. I set up 3 servers and
ran the sample and randomly closed and restarted the three servers. Most of
the time the esb sends the message to the correct server according to the
order. But sometimes I get the following message from the client
application. After getting the message, everything halts.
[java] Request: 3838 ==> Response from server: Myserver1
[java] Request: 3839 ==> Response from server: Myserver1
[java] javax.xml.stream.XMLStreamException: ParseError at
[row,col]:[1,1]
[java] Message: Premature end of file.
There is no error message on the esb. I tried to restart the client app,
but I get the same message. It works when I restart the esb. Is this a bug
or is this the way it should happen? Is there any explanation for this? I
found a similar kind of issue for sample 58 in [1]
I get the following message on the esb every time I restart the client app
(servers are all up).
