Hi there,
I am trying to setup media-streaming on two servers, one for the darwin
server, the other for the faban client. The installation was quite smooth,
however when I ran the workload with run-test.sh, it always gives me the
following error on the client:
Dec 24, 2013 4:20:56 AM com.sun.faban.driver.engine.AgentThread logError
WARNING: StreamDriverAgent[2].946.doGetMediumLow: Cannot run program
"/home/hailong/media-streaming/faban-streaming/streaming/rtspclient.o":
java.io.IOException: error=11, Resource temporarily unavailable
Note: Error not counted in result.
Either transaction start or end time is not within steady state.
java.io.IOException: Cannot run program
"/home/hailong/media-streaming/faban-streaming/streaming/rtspclient.o":
java.io.IOException: error=11, Resource temporarily unavailable
at java.lang.ProcessBuilder.start(ProcessBuilder.java:475)
And also I notice on the darwin server, the statistics are always zero as
the following:

It seems the darwin server has not received the client requests at all. The
firewall on both of the servers has been shut down. The workload
configuration is as follows:
<!-- The scale of the benchmark run, the driver definition
defines the number of threads for each driver scale
and each driver type. -->
