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.
