Migrating 9,000 apps to 72,000 database instances on 12 new domino servers. Got about 85% of them done via FTP (dont ask) and now going through them to check for replication problems.

So - writing myself a replication event monitor/consolidation tool, which will take one of a number of actions depending on the replication failure type - manual replication, or a fixup/compact of the database.

Technically not difficult, but just logistically immense when dealing with 50+ servers. Should keep me out of trouble for the next day or so..
