Exception when CPU Sampling enabled

Postby moffit » Fri Mar 22, 2019 10:23 pm

Hello,

I'm using YourKit 2018.04-b86 under Java 1.8.0_172 64 bit (both client and server).

Remotely profiling a Spring Boot 2.x application with embedded Tomcat 9.

Connection and normal telemetry has no issue. If CPU sampling is enabled, a UI dialog is immediately shown with the stack trace at the end of this post. The UI becomes unresponsive at this point and consumes about 25% CPU indefinitely. It must killed from the task manager. The log file appears to be full of these same errors (some kind of loop must be happening that continuously encounters the error). Running the server agent with sampling immediately enabled also produces the same result.

I cannot post the stack trace - can I attach it somehow?
