I am also experiencing this bug in 7.2

I setup top to run every minute from crontab to diagnose an unrelated
problem.
carbon# crontab -l

* * * * * top -a -I -j -t -n -osize >> /var/log/top.log ; echo
'-----------------------------------------------------------------------------------------------------------------------------'
>> /var/log/top.log
and I'm getting emails containing "kvm_open: cannot open
/proc/<number>/mem".
The error is not generated every run. It runs every minute, and the last
3 errors I have are 10:18, 10:27, 10:32 (current time, 10:47)
