This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.
Fix for this won't be enabled by default - it isn't applicable for s390x architecture and it is kind of performance tuning ~ it won't fit everybody.
In rawhide it's now possible to use numactl to launch mongodb server when using systemd service files. It can be done by editing /etc/sysconfig/mongod or /etc/sysconfig/mongos files - NUMACTL variable is used to launch mongod/mongos server.
(upstream recommended value is provided in comment in sysconfig files)
