Description (partial)


Under certain conditions, a stale VTY could be created in the CSG which can be detected using the output of SHOW USERS command.


The issue could potentially be seen in CSG2 releases released before 09/30/2009. One way of hitting the stale VTY is to disconnect the physical cable connecting the CSG module to the network using which a user would normally telnet to CSG. The issue is not easily recreatable though.
