Conflict resolution on Syncrepl

Hello all,

This is mostly a theoretical question. I currently have some OpenLDAP multimaster clusters (using syncrepl and mirrormode) and although it never happened before, what would happen if two (or more) masters received a write request exactly at the same time? The entry would have the same entryCSN on both servers and the contextCSN would be updated at the same time? Would this lead to a situation where the servers were actually out of sync but they would "think" they had the same entries?
