Hi,

We have one customer that wants to get replication implemented. We've set it up 
in house and it seems to work well.
The trouble is there are 10's of thousands of users and all sorts of concurrent 
activity. They're on M16 and a few times per month, we get the 'ERR_554 double 
get for block' and then we need to restore.
We have an automated way of doing this now so it's not too disruptive when it 
happens.

My question is, would adding replication just add more concurrent activity to 
the servers and lead more frequently to the ERR_554 situation?

Also he's asked to upgrade to M20 but my hunch is that for this issue it won't 
matter much because we're still on JDBM?

Finally, we're eager to test out a release with the Mavibot backed. I'm sure 
it's possible to build ourselves but we're trying to keep the moving parts to a 
minimum
and use only ApacheDS releases.

Thanks for all your excellent work
Carlo
