I have SharePoint running on a server farm configured with 1 app server, 2 WFE's and 1 DB server. I have 4 applications in SharePoint which are (seemingly) working properly.
What is strange, however, is that only 2 of the applications' worker processes (running under their respective unique service accounts) are executing on the web front ends. This makes me think that the front ends aren't doing their job for the remaining 2 applications. Should I be concerned?
Also I'm not sure if 'load balancing' is the proper term for what should be happening here, though it seems to fit.
