Failed to renew security token

I tried testing the nodejs server using Prosys java sdk 2.0.2 evaluation version. I used the SampleConsoleClient to connect to the server. After awhile, I received a recurring error on the client:

Client console output:
02/05/2015 15:15:01.560 ERROR 66 Failed to renew security token.
org.opcfoundation.ua.common.ServiceResultException: Bad_UnexpectedError (code=0x80010000, description="Sequence number mismatch")
at org.opcfoundation.ua.transport.tcp.io.TcpConnection$ReadThread.run(Unknown Source)
ServerState changed from Running to CommunicationFault

Test server console output:

Which side would be causing the problem?
