iPhantoms are any background that perform interactive operations, such as opening a socket or device. They consume a licence.
FWIH some time back a couple of naughty sites were buying small numbers of users and opening ttys directly with phantoms so IBM blocked that. Now it catches all of us who legitimately want to make a web service or similar call in the background.

On our systems, we will have 100 to 200 phantom processes, i.e. background processes, running at any given moment. When I look at them via LISTUSER, they will be split approximately 60/40 between phantom and iphantm. All were started using the PHANTOM verb. I can't discern a difference, and I can't find anything about it in the 7.3 UniData documents. A search for "iphantm" has no hits. This comes into play because it seems that SYSTEM(514) includes iphantm sessions in the count, but not phantom sessions. We have a monitoring program that warns us if the number of users approaches the configured license limit, and it uses SYSTEM(514). We built in for it to allow for a configurable amount of phantom processes. If phantom processes may or may not be included in SYSTEM(514), our monitor program isn't as accurate as it could be. It seems to me that neither phantom nor iphantm should be included in SYSTEM(514). HELP for SYSTEM(514) states that it returns the number users currently logged in and does not include phantoms. Presumably, this is the number of licenses in use. Do iphantm sessions use a license?
