"Zombie" sessions can cause CR backlogs
There is a small risk that a session can hang during logout, causing the stone to be confused as to if the session is alive or dead, hence the nickname "zombie" session.
These zombie sessions can still hold on to a transactional view and cause a CR backlog. The zombie may not respond to a System stopSession:, and even when the OS process is killed, the stone may still think the session exists.
The following tools may be useful in dealing with zombies:
System allZombieSessions
System allZombieSessionsRefOldestCr
System stopZombieSession: <sessionID>
