All,This happens on all of our CentOS 7 VMs.  but as stated in the email trail, the file softlockup_thresh does not exist.  Should it be added?  What is the best way to get rid of this behavior.
Thanks in advance and sorry if I missed something along the way.KM

Yes, I tried it, but does not exists:

vmguest # cat /proc/sys/kernel/softlockup_thresh
cat: /proc/sys/kernel/softlockup_thresh: No such file or directory
