A message stating "BUG: soft lockup" is output from the kernel. How can I resolve this?

In Linux OS environments such as CentOS, there are cases in which messages like the following are output form the kernel to log files such as /var/log/messages.

kernel: BUG: soft lockup - CPU#1 stuck for XXs!

These messages are output when the watchdog thread for soft lockup has not been executed for a certain period of time. This will not result in problems such as stoppage of the kernel, so the message can normally be ignored. However, if the message is output frequently, you can suppress output by adding "CONFIG_LOCKUP_DETECTOR=n" to the GRUB settings file and using the grub2-mkconfig command to enable settings.

# echo "CONFIG_LOCKUP_DETECTOR=n" >> /etc/default/grub
# grub2-mkconfig
