EverQuest2.exe Instances Running After Logging Out

Some players have noticed everquest2.exe instances keep running in the background after they have logged out. Aerendar from Quality Assurance would like to get to the bottom of it, and asks:

Could we get a little more info from you regarding your system specs (DXDiag and MSinfo would be extremely helpful in looking at this further and to see if we can determine a commonality between users)?

He adds:

We’re also interested in how you’re getting into game (which launcher/portal).

If you have experienced this problem, please post in the relevant thread. If this is an old issue resurfaced, we can postulate, but your help would be greatly appreciated.
