...  But I saw a presentation at the Boston MySQL Meetup.com
group about how to do master-master in mysql 5.  We're about to
implement this in the next few weeks.  ...

I've run into issues with crash recovery in master-master mode:

 - master A is at position X
 - master B, replicating from A, gets to position X
 - master A syncs to its filesystem that it's at position X

 - master A receives some inserts, and is now at position Y
 - master B, replicating from A, gets to position Y
 - master A crashes before the position gets synced to filesystem
- master A gets rebooted, recovers from innodb log, but has itself only marked at position X - master B requests position Y from master A, but that position doesn't exist yet, so replication breaks.

Perhaps someone here knows the proper recovery procedure at this point?

best,
Jeff
