a) Please don't resend your emails to the list. The first one got through
fine, which you could easily verify by looking at the list archives.
b) Not enough information provided here to go on. Are all server IDs
unique? Are all syncrepl clauses unique per DB? Personally I've never
found ntpd particularly good at keeping clocks in sync. I've generally
resorted to running ntpdate frequently out of cron, particularly for VMs.
