Configure User Sessions

Solution: Use the SessionsPerUserMax or SessionsPerAnonymousUserMax parameters with the Set-SPAccessServiceApplication cmdlet.

The SessionsPerUserMax and SessionsPerAnonymousUserMax settings determine the maximum number of sessions that can be created per user. When the limit is reached, older sessions are deleted to make room for new ones. The default per user is 10, whereas the default per anonymous user is 25. An entry of -1 denotes unlimited, and the valid range otherwise is 1 to the maximum integer value allowed. Listing 23.15 shows an example of setting both user session values.

Listing 23.15. Modifying the Number of Sessions Per User

Set-SPAccessServiceApplication -Identity "Access Services"
-SessionsPerUserMax 5 -SessionsPerAnonymousUserMax 5

Stale sessions will indeed continue to take up resources until the cache timeout is reached. If users are constantly instantiating new sessions, you might want to decrease these maximum session settings.
