JVM crash problem on running performance monitoring

Postby vipnaik » Wed Jan 03, 2018 3:58 pm

For monitoring real time performance of JVM we have activated YourKit agent at WebSphere JVM by adding below mentioned JVM generic arguments.
-agentpath:/data/yourkit/YourKit-JavaProfiler-2017.02/bin/linux-x86-64/libyjpagent.so”. After adding this argument and on invoking profiling JVM gets crashed after few minutes.

In native_stderr.log we are getting below error:-

What is the exact version of IBM Java you are using? What is output of "java -version"?

Please send us to support@yourkit.com the crash log in full (from native_stderr.log; please also check if the JVM creates separate crash log files), and the profiler log file <user home>/.yjp/log/<session name>-<pid>.log
