Do you see data for Server24 in the statrep.nsf on that server? If so, then its additions to statrep.nsf are not replicating to Server16. Is there no information about Server24 in its statrep.nsf? Is the design of statrep.nsf on Server24 older?  If you remove statrep.nsf on Server24 and allow it to be recreated, do you then see data in its statrep.nsf? Does the console.log show any issue when the event task is reloaded?

Are you sure that the server that is not collecting stats is listed in the collect from field (group is a good idea) and the server task collect is running on the server?

- No. There's no statrep.nsf on Server24, or Server24A. It's Server16 that's doing the collection, and it's collecting stats from the other servers without a problem.

The statistics collection setting is 'all servers in the domain' - for all the other servers, statistics are being collected successfully by Server16, and the reports are being created in the staterep.nsf on Server16.

Maybe something got stuck with Server16? I'll try re-creating the databases on Server16 from scratch and see if that cures it.

Sometimes I've run awry of the profile setting in the Address Book not being the "right" domain.
