I get an error when using jmeter with one master and one remote node. I did this steps:

  • Java & JMeter versions are the same (whith JMeter plugins)
  • I started the JMeter Server in the remote node
  • I added the remote node IP to the properties file of the master
  • I startet JMeter on the master and started the test script via remote start (the command line of the master contains "Using remote object …" with the correct IP

After that JMeter freezes and after 7 minutes I get the error Message "Engine is busy - please try later".

The Log of the master is:

Did I forget to add some configuration or where is the problem?

Thanke in regards...

  • I'm getting something similar. Running GUI with a single remote; the remote says 'starting the test...', but the GUI gets no feedback at all, and after a delay, I get the same "Engine is busy" error. Eventually the remote finishes the test with no other errors, but still no feedback. – Synchro Aug 26 '14 at 12:16

This error is because of the slaves are still executing previous test plan.

i would suggest.

  1. while stopping the jmeter tests , use 'Remote Stop all' option from master, which kills the running threads on remote/slave machine process.

2.Restart[relaunch the "jmeter-server.bat"] on the slave/remote jmeter process and start the test.

Your problem is that the runners(slaves) are still running the test from your first start command even though you tried to end the test. Previous answers on Stack did not work for me in solving this problem so here's my solution:

On every runner(slave) do the following:
1. kill -9 `pidof java` This will kill all Java processes so be careful if running other applications.

2.cd into apache-jmeter/bin directory and type ./jmeter-server & This will restart your runners(slaves) as jmeter-servers so they are ready to receive communication from the master.

Then you should be able to successfully restart your test from master.

IN your case , it seems you triggered the test from master twice. So the message is saying to you, a test is currently running on slave , cannot start a new one.

How do you start test from controller ? and how do you start jmeter-server from slave node ?

  • I started the test with Run -> Remote Start -> IP of the remote node. So the client shouldn't run the test. I started the server with "jmeter-server.bat" with using a proxy. – SLo May 07 '14 at 10:02
  • Do you still reproduce issue every time ? If so try laucnhing test using non gui mode which is by the way a best practice. GUI mode is only for Test Plan debuging not load testing. – UBIK LOAD PACK May 07 '14 at 16:58

Error in NonGUIDriver java.lang.IllegalStateException: Engine is busy - please try later

This error occurs while running JMeter in non-GUI mode. JmeterApacheJMeter.jar process aborts on master without sending STOP signal to slaves to specify the test status.

Perform steps below to fix the issue on Slave machines:

Step#1 : Kill any running JMeter-server agent process on JMeter Slave/s

    ps ax | grep "ApacheJMeter.jar" | awk '{print $1}' | xargs kill

Step#2 : Start JMeter-server process on Slave/s

    cd apache-jmeter-folder/bin/; ./jmeter-server &

Now resume your performance test on JMeter master.
