How far behind does your replication lag when you observe the lost
rows?  I have alarms go off via nagios when our replication falls
behind by more than 180 seconds (because our customers start to
notice).  Our normal lag is not more than 5 seconds or so, but
occasionally we get up to 10+ minutes when doing maintenance cleanup
jobs.  I don't have evidence of ever losing any data.
