Unable to Check Virtual User... Log detail as below
2016/05/03 12:26:58 WARN - neoload.Runtime: Can't start the Load Generator localhost com.neotys.nl.controller.hb: Failed to start Load Generator on localhost. The Load Generator process has been created but has not registered after waiting delay (key "lg.start.delay" in agent.properties). : an error occured while communicating with 'localhost'
This issue can have different root causes. Does it happen all the time or sometimes?
To troubleshoot that issue, the best is open your task manager when starting a check virtual user and check if a "java.exe" process is able to start.
If that process is there then the issue might be some latency and the process takes too much time to start. You can modify the "lg.start.delay" value like described in the error message.
If the process does not show up then even you have a firewall or there's a memory issue where the JVM cannot allocate enough memory. In that case, you should use a remote load generator.
