I'm getting this problem sporadically on three unrelated apps on three
different servers (all hosted by different companies). We only received
reports of it happening last week.
The symptom I am seeing is the server will occasionally send back a new
session ID cookie. Subsequently, the browser will continue to send back
several session cookies and the server will randomly choose between the
sessions.
I am currently in discussions with the hosting providers to find common
factors. In particular looking into the app pool worker process numbers to
make sure they're all at 1 process.
The fact that the sessions that apprently get 'replaced' get dug up again on
subsequent requests indicates they aren't being totally recycled.
