"There's no application running at localhost with profiler agent"

Post by tklock »

Dear Yourkit support team,

I encouter this error message when I start to capture memory snapshot in HPROF format via JVM built-in dumper :
There's no application running at localhost with profiler agent configured to listen on port 50951 or profiler agent is incompatible with current version of profiler
I use YourKit Java Profiler UI v2018.04-b88 on Windows 10 with Java v1.8.0_172 64 bit and YourKit Java Profiler Agent v2018.04 on Linux Red Hat Enterprise Linux v2.6.32-504.el6.x86_64.

Do you have any clue to help me resolve this issue ?

Capture seems to work after increasing socket timeouts of the profiler UI in local /.yjp/ui.ini file :
-Dyk.controller.connect.timeout.ms=60000
-Dyk.controller.read.timeout.ms=60000

Hello,

Thank you for sharing the solution.

Please consider using the latest profiler version 2022.9 instead of version 2018.04 which is no longer supported.
