Hi, We recently noticed high CPU utilization from one of the WLSDM thread within the managed server process.

Here is the trail of the issue:

  1. Top command on the server to see which process is taking the heavy load.

  2. Identified the process id as 9719. The following is the result of the command “top -H -b -p 9719”

  3. Identified the top thread id as 9951. Find the hexadecimal for this.

  4. Check the Thread id in the thread dump taken exactly at the time of checking the process top command in step 2 above.

Can you please check why this WLSDM thread is hogging lot of CPU?

Thanks,
