First I would ask what version of Domino were you on before 8.0.2. Then I would ask if you ran complete maintenance on the server before the upgrade and then after the upgrade.Compact -c -i
Updall -x
Fixup -f
If a consistency check is happening each time you restart the server then that tells me that the databases are reporting some sort of an issue each time. The first step would be to run the maintenance above and see if this stops the consistency checks.
I strongly do not recommend that you use any parameter to avoid the consistency checks. To do so would risk an unstable environment.
