To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.

But i tuned node system before install Qlik:
mcedit /etc/rc.local
echo never > /sys/kernel/mm/transparent_hugepage/enabled
mcedit /etc/sysctl.conf
net.core.somaxconn=15000
I'm trying to recreate kubers cluster on clean installed servers and get same errors
