\"Connection<\/a>When you try to connect to the admin console (dashboard) of a NetScaler X you get the error \u201cConnection limit to CFE exceeded\u201d. If you login via SSH is seems the credentials are invalid.<\/p>\n

Users with a different username are able to login. In this example vtsha_admin<\/em> is unable to login, nsroot<\/em> can login..<\/p>\n

<\/p>\n

This is because the user you are trying to login with has 20<\/strong> active system sessions. You can verify the active sessions in the admin console via NetScaler > System Information > System Sessions<\/strong> or via a SSH sessions and the command<\/p>\n

show system session -summary<\/pre>\n
\"System<\/a>\"show<\/a><\/p>\n
The screenshots are to illustrate there are multiple sessions. The error is only seen with > 20 sessions.<\/em><\/p>\n
<\/em><\/p>\n
<\/em><\/p>\n
Release sessions<\/h1>\n
The active sessions can be released in the admin console by selecting the session and clicking on Cancel Session<\/strong> or via a SSH session and the command<\/p>\n
kill system session (SessionID)<\/pre>\n
\"Cancel<\/a>\"kill<\/a><\/p>\n
 <\/h1>\n
