Directory Assistance Databases opened multiple times by server?

I have directory assistance enabled in my domino domains. When I look at some of the servers within the domain, specifically the “Database Users” on that server, I notice that 1 or 2 of the Directories listed in Directory Assistance are opened multiple times. ie. I’ll see “webusers.nsf” is opened by (an)other server(s) in the domain, but there are 30-50 of these ‘in use’ conditions, although many will show the Minutes Idled at 100’s or 1000’s of minutes.

Have I missed a setting that would drop these idle connections? As I’m looking at one of my servers it has 17 connections to the same server, for the same Database (named in Directory Assistance), with varying Idle times of 0 - 1363 minutes.

Thanks,

Brian
