n-way multi master and mirror mode

i have a n-way multi master replicated directory, and i currently have mirror mode turned on. i am getting events in my logs about deferring operations (too many executing, etc) and want to know if i am causing these with mirror mode. the reading i am able to do on the topic seems to indicate that mirror mode is only necessary in provider/consumer replication, but i wanted to clarify that. is mirror mode necessary for n-way multi master replication? am i safe to turn it off, if it not needed?

thanks in advance,
