Yourkit UI throwing "There's no application running at localhost with profiler agent configured to listen on port" exception

I am trying to profile remote applications that are deployed within Jboss. So far I can connect to the remote server and see my applications, I am also able to connect to the applications. But when I click "Start CPU profiling", it takes really long time and most of the times results in the following exception:

There's no application running at localhost with profiler agent configured to listen on port 59462
or profiler agent is incompatible with current version of profiler

Although sometimes (rarely) it does start the profiling and give me the results what I want. But I am not able to understand this inconsistent behaviour and I also don't understand why does it give me an error saying "no application running on localhost ..." considering I am trying to profile a remote application.

Snippet from the machine where the UI is installed:

It would be great if someone can explain and guide in this matter.

Thanks in advance!

So finally I was able to solve my problem with the help of Yourkit support team. Here is what they told me:

Please try to increase socket timeouts of the profiler profiler UI by specifying -Dyk.controller.connect.timeout.ms= (default is 5000 ms = 5 s) and -Dyk.controller.read.timeout.ms= (default is 30000 ms = 30 s) in /.yjp/ui.ini

For example, set

-Dyk.controller.connect.timeout.ms=60000 -Dyk.controller.read.timeout.ms=60000

I hope it is helpful to others facing the same issue.

I've just faced the same strange behavior. A day ago I manged to profile the app remotly but not today. I connect to the remote JVM through SSH and any settings has not been changed.

It is also inconsistent for me. Do you happen to know why does it refer to a specific port number in the exception? and which machine does it mean when it says "localhost"? Is it localhost for the agent or localhost for the UI application? – Fungistat
