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

[Anonymous]

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

Does anybody know what these threads are ?

What can be causing the high CPU usage by these ?

Kind regards

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:

Let us know if it helps.

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
