A prerequisite (or more than 1 prerequisite) can be set on a Dynamic 
Update transaction by the client or client app, and if the prerequisite 
isn't met, then the update is not performed.
Whatever app is generating these particular Dynamic Updates is failing 
some of them due to the fact they prerequisite(s) they set weren't met. 
This is probably harmless, but if you want to double-check, then consult 
the logs and/or documentation of the relevant app (probably a DHCP 
server) to see what prereqs it is setting, and what it does in the case 
of a prereq-based failure.
