Thanks Remco, that's a reasonable response.  In other words, the number of
processes will be directly related to how many processes/sessions are
active at any one time.

Looking at a graph of several hours of activity, it appears that when my
TSM 7.1.3 server is idle, there are on average 65 connections from the
dsmserv account.  And right now, I see 4 Migration, 8 Identify Duplicate
and 4 Space Reclamation processes running, and connections hovers between
125 and 150.  During a database backup the connections were pinned at ~175.

I'd be interested in hearing about other installations' metrics, if anyone
is interested in sharing them here.

Best regards,
