Hi there,
Just ran into this myself -- Could be related to CSCvp95742 (Futures timeout error - High CPU). My MSO is running 2.1(2g). Did the following in my specific case (you'd have to see which task is causing high CPU % in your case):
[root@msc-1 ~]# docker stats --all | grep 77

[root@msc-1 ~]# docker service update msc_executionengine --force
msc_executionengine
overall progress: 1 out of 1 tasks
1/1: running [==================================================>]
verify: Service converged
I was able to move forward with my schema configuration afterwards.
Hope that helps.
