Runtime ESB High CPU Load - caused by webconsole - gogo ?

When looking at the CPU load of our server where the Runtime ESB is running on we noticed a high CPU load.

We don't know if this started at a certain moment. but it seems that it is already going on for a while.

 

When running 

ttop --stats=tid,name,state,waited_time,waited_count,blocked_time,blocked_count,user_time,cpu_time,user_time_perc,cpu_time_perc,lock_owner_id,lock_owner_name --order=cpu_time --millis=300

on the shell prompt we get the below CPU usage within the container

when checking the threads we found that below threads seem to give the load

 

threads 250886755 
Thread 250886755 Thread-167281465 RUNNABLE Stacktrace: java.lang.Thread.isAlive line: -2 java.io.PipedInputStream.read line: 308 java.io.PipedInputStream.read line: 377 java.io.InputStream.read line: 101 org.apache.karaf.webconsole.gogo.GogoPlugin$SessionTerminal.run line: 247 java.lang.Thread.run line: 748 threads 324531013 Thread 324531013 Thread-216370392 RUNNABLE Stacktrace: java.lang.Thread.isAlive line: -2 java.io.PipedInputStream.read line: 308 java.io.PipedInputStream.read line: 377 java.io.InputStream.read line: 101 org.apache.karaf.webconsole.gogo.GogoPlugin$SessionTerminal.run line: 247 java.lang.Thread.run line: 748

Does anybody know what these threads are ?

What can be causing the high CPU usage by these ?

 

Kind regards

Re: Runtime ESB High CPU Load - caused by webconsole - gogo ?

Hello,

What's platform are you using?

You could augment the JVM RAM usage and the Memory usage of JVM on file SETENV.BAT located in (runtime folder)/Container/bin

For more information, please have a look at this documentation:

We indentified in the mean time that it probably was related to a corrupt installation of the webconsole.
Uninstall / reinstall of webconsole + full reboot of the machine was necessary to solve the issue.

Kind regards
