JMeter remote test fails with error message "Engine is busy - please try later"

Question

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...

Answer 1

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.
