RHEL7 error on bootup with systemd and udevd.service

Have a test system VM of RHEL 7.2 and when starting it up in Virtual Box, notice that it is having the following errors when booting up:

systemd[1]:  systemd-udevd.service has no holdoff time, scheduling restart. 
systemd[1]:  Stop by pending for unit, delaying automatic restart.  

These error messagse loop over and over again.

If I reboot the VM, it will boot up without these errors and eventually go to the logon screen without issue.

Was wondering if anyone else had seen this and the reason behind it.

thanks
